Dont know bout you, but this is BY FAR THEE WORSE Air Conditioning I have EVER had. And being an old bastard I've had many.

I mean chit even on a mild day it takes FOREVER to cool the truck, yes I know it's Black but almost every vehicle I've ever owned has been Black.
My complaint is the blower simply doesnt blow strong enough. I can remember one or two vehicles along the way that you'd once in a while use the Re-Circ button to increase the Blowing Power, but with the Jeep if you dont use it you dont hardly get any flow of air, even on high ???

My Stang prob blows 2 to 3 times stronger and is a 1/3 of the interior size, (and also is a hell of a lot colder for that matter)

Anyone else find the AC not nearly enough ???
Anything that can be done to get more Blower Power out of it ???

yes, i have noticed recently in the 100+ temps that our ac does not blow enough. it almost seems that there is not enough insulation on the headliner because the upper part of the car gets very hot. i always seem to find a warm pocket to the left of the normal driving position. move your big melon around in the car and you will see what i mean

I was beginning to think there was something wrong with mine; like it needed recharged. It sure isn't very effective in these 95+ degree days were having here in central PA.

Same here, and I should add that my outside temp readout has been around 103-105 for the last week at least, once I got the side windows and windshield tinted it made a huge difference, it's livable now.

If you press the button that is to the right of the a/c button, witht he circulating symbol on it, it will blow a lot harder. I always make sure I have that one on. It works great for me. I just hate how loud the blower/fan are outside the car.

I compared it to my 2003 Tahoe and it's not even close. The a/c on the Tahoe is twice as cold as the Jeep's. But, I've never loved any vehicle like I love this SRT!!

Definatly noooo goood. But everything else makes up for it.

Lately, we have been having hot and humid 100 degree days, and I only have to keep my AC on the lowest level. My SRT8 is only a month old, could this be an issue with earlier models?

It must be your humidity. Here, where it hit 118º a few days ago, I was very happy with the SuperJeep's A/C. Now our humidity hit 33% one day, but is usually MUCH lower. Avg. humidity is less than 10%.

I'm sure some of it is personal temp preference.
I'm just comparing to my other current and past cars and it doesn't put out the volume or temperature of their a/c's.

Mine is the same way. Anything short of the coldest setting on the temp dial results in warm air coming out of the vents. ?Temp sensor problem?

It's between 85 to 100 yearround where I live and I've never felt the system was inadequate. Actually I never put my temp under 72 otherwise it gets too cold. But there's some tricks you have to follow.

- if you leave her in the sun it's going to take a few minutes before you get nice cold air, unless you have a garage or fully covered parking spot... then she blows cold almost instantly.

- if you ever have to park in the sun get the Mopar windshield shade, it keeps the interior especially the dashboard a bit cooler so the system doesn't have to work as hard when you start up. I recommend the Mopar one because it fits perfectly and it folds up quickly, unlike the aftermarket ones thats you have to roll up and velcro.

- window tint can make a big difference especially if you have the good stuff... CERAMIC tint is 10 times more expensive but has the highest UV heat rejection. Don't forget to put some on the moonroof, and always keep the moonroof shade closed.

Another thing to consider is the color of your ride. A big black box sitting out in the 100º+ sunshine is going to be hotter inside than a big silver box. In AZ, black ain't the best choice.:D

yae

i had a 2004 escalade ac was better

Last week it was 100+ here in NYC and my a/c was still ice cold, keep the outdoor air shut the button on the right for air recirculation and keep the dial all the way down for temp, remember the temp dials are not for how cold the air comes out but what temp you want to maintain in the cabin. Hope this helps someone.

What setting do you have it on? I run the far left rotary dial on either low or high auto and the far right rotary dial on auto. The 2 comfort zone dials are set at coldest to start out but I usually have to adjust them warmer after a few minutes. The temps around here have been in the upper 90s with high humidity.

I run the fan in manual, air recirculating, and after the car cools off start adjusting for your comfort level.

Have you tried the auto setting? I'm pretty sure that mine will enter recirculating mode on it's own until the cabin has cooled down & then do whatever is necessary to maintain the set temp.

I have no complaints with this system. Temperature has been well over a 100 the past week and it has been nice and cool inside the jeep. I haven't even run it at the highest setting.

Wow lot of mixed answers, but glad to see I'm not alone ???

Definatly noooo goood. But everything else makes up for it.

I AGREE :p

Took mine on a 8 day trip up into the mountains a few weeks back and finally got to put some REAL miles on it. It was great to experience how comfortable and AWESOME it is on the open road too http://www.lightningrodder.com/forum/images/smilies/023.gif
Not just the Beast it is around town http://www.lightningrodder.com/forum/images/smilies/banana2.gif


I know here in the NY area we are DEF having some of the hottest temps we've had in a while, but even a month ago I had the same complaint.
It's bad enough the temp is def NOT as cold as other vehicle's, but it's the lack of power the Blower has that I cant understand ??? Everytime I get in it I sit there messing with the vents trying to find a spot where I can feel a nice cool breeze. I do know Black makes it harder to cool down but I think the Blower is way too weak for the size of the vehicle.

Good example is today I'm working on the Mustang, (installing a larger MAF), took it to my Tuner to get a retune, and then went back in the SRT8 to get another part while I had it half apart. The Mustang was so frigging cold I shut the AC off numerous times to get the cold off me, and constantly I find myself taking it off Max AC and even then using a lower fan speed.
BUT when I took the SRT8 back I sweated my butt off the whole 15 minute ride there, "with it on the highest setting for Temp, Fan, and using Re-Circ".


As said I guess it's a small price to pay to drive such an awesome vehicle.....
At the Tuners shop today he had (2) Shelby Cobra's, some Lightnings, Stangs
and some other really nice vehicles, meanwhile everyone there was drooling all over the Jeep ;)

My remote start automatically starts the car once the inside temp. goes above a predetermined temp. that I set. It goes on for 10 minutes, cools down the interior and then shuts off until I deactivate it. This is the best feature of my alarm/remote start.
I found this helped the "sauna" feeling you get once entering the car.

I dont have an SRT8, but its been the same in my Jeep.

Just remember, that if you get in your Jeep and have it on Re-circ, your trying to cool down super-heated (140+) air inside your cabin. Start with your air comming from outside, and then once its cooled down, then recirc.

Actually that is not a good thing to do, throwing 140+ degree air over an evap coil will raise suction pressure and push oil out of the compressor and overheat the motor windings in the compressor due to high suction pressure/temps, the long term effect of this is compressor failure. Open your windows let the hot air out, recirculate the air in the cabin and when it starts to get unbearably cold open the recirculating door for outside air, or adjust the temp settings to your liking.

.... remember the temp dials are not for how cold the air comes out but what temp you want to maintain in the cabin.

Ya, that's the way it's been on every ride I've owned, up till this one. When I adjust the temp dials, it immediately changes the temp of the supply air. If I set it to 70*, I swear I get 70* supply air, and I design HVAC systems for a living so I'm pretty good at guessing temps. I was very surprised and disappointed by this when I got the car, but I've grown used to it and I don't really notice anymore.

Mine is the same way. Anything short of the coldest setting on the temp dial results in warm air coming out of the vents. ?Temp sensor problem?


Exact same problem I am having and it has only 200 miles on it. This was happening when it was only 78 degrees outside. it was warmer side than out and the temp was on 68

Maybe you should have the charge checked? My A/C control works dead on accurate or as close as can be, and is ice cold, and make sure the compressor is running continuously, physically look at it and see that it is running and not short cycling, if it is short cycling your either going off on low pressure (No gas or not enough gas 134a) or high pressure the fan is not running or not running long enough, with these cars as soon as the A/C comes on the fan runs continuoulsy. Check the suction line and see if it is cold or not. I would not hesitate to bring these back to the dealer for service, sounds like some of you guys have real problems with the A/C system. Do it before warranty expires and then you have to pay for it. Like I said before the A/C in mine freezes me out and it was 100+ last week and I still froze.

BTW Ide have the dealer do the TSB flash first before touching the refrigeration system it may just need the update.

If you go from the lowest cold setting to 68 or 70 you will get a burst of warm air with these temp controls for a second until the sensor readjusts, especially if it has gotten cold in the cabin, you have to remember the dial temps are for cabin temperature not supply air temperature. Its a huge difference. If you want continuous cold air all the time leave the temp dial buried past the lowest setting.

(1) Any increase in suction pressure & corresponding increase in head pressure due to hot start-up will have almost zero affect on oil location.
(2) Automobile A/C units don't have motor windings to overheat. They are belt driven off the crankshaft pulley. Whether the compressor is of radial, rotary, or piston design the only windings involved are in the external clutch pack.
(3) Having the windows down to let fresh air in & 140* air out is a good idea but cut the A/C on immediately, you'll do no harm to the compressor.

I think the ac in the jeep is cool enough..we have had a week of smoking hot 90+ days. You should feel the factory air on my 64 Impala, If you think the ac is bad on the GC.

I have found the coldest air and best temp. setting come from leaving both dials on AUTO. If i want more blower, i set to auto high and if i want less, auto low. But i always leave the directional selector in AUTO. works the best.

Finally, somebody agrees with me. Have any of you guys that are experiencing problems tried leaving both dials in auto?

all last week in NJ temps @ 95 to above 100 with 60% humidity and my AC blows ice cubes!No problems here

I disagree about the oil not being pushed out as little oil as there may be in the car systems prolonged high suction pressure is not recommended for any compressor car or residential/commercial. High head will not really effect oil location but can cause compressor failure sooner or later if not corrected. Touche on the clutch correction. Brain fart!

Hey Guys,

Chiming in a little late, but wanted to share some info.

When we bought our SRT8's (in Nor Cal during the 110+ heat wave), we had the same complaints about the AC taking forever to cool down (during the test drive). Simply put, blowing hot air.

When the salesman turned the knob on the right to "auto" and set the temperature settings to 70 degrees (or whatever); the A/C started blowing cold air almost immediately.

Throughtout the heat wave here in California, the A/C kicks in immediately on this setting.

Leave your right knob on "auto", set your temps and use the left knob to control the fan speed. I don't worry about pressing the A/C button or anything, it's just autoset and works like a charm.

I noticed that if I switch the right knob to something other than "auto", warmer air starts coming out of the vents. (The same results on both the GCSRT8 and 300CSRT8)

Use "auto" and you'll love your A/C.

I've been following this thread the whole way and would like to make an observation. All of the owners who have NOT reported any problems have been running their controls in the Auto position. Those that HAVE been reporting problems have been manually adjusting their controls. For those "manualists", why not try the auto settings & see if the AC works better. If it doesn't work acceptable in the auto position, then make an appointment at the dealer to get it checked because there is a problem with your AC.

I never said I had a problem. I said that the a/c in the Jeep doesn't blow the amount or the temperature of the Tahoe I just got rid of.

I have mine set in outo except when I have it on defrost. Hot or cold does a very fine job.

I have not really used auto alot but it freezes me out regardless.

I run my A/C on manual and it still blows cubes:D

ditto to the "non auto = still very cool in blazing hot SoCal" posts

Exact same problem I am having and it has only 200 miles on it. This was happening when it was only 78 degrees outside. it was warmer side than out and the temp was on 68

Guess what? Brought it in for the 6000 mile oil change, and mentioned the problem. The dealer stated that there is a factory TSB about this problem, requiring a reprograming of the climate control system. Since then, it's definately better, but still not perfect (I'm now within 3 degrees of what I consider normal (and thus consistent with our other two vehicles), but much better than having to set the absolute coldest setting on the Jeep to get true conditioned cold air during hot outside temps.

The TSB is for fixing the the amount the interior temp indicator recognizes as a "change" of input or something like that. It will not make the A/C blow colder.

I still get the absolute best results with both knobs set to auto.

I also took it to the dealer and they did the TSB. In fact they called chrysler and an engineer actually called them back. Basically they have the tsb for now, but they are still working on solving the problem. I will keep you posted if they find a fix for the problem.

I'm late to join this thread but my AC is fine (it's been 102-106 here daily). What I did discover is that I don't get very cold air if I set the fan control AND the vent control both to AUTO. I get great cold air if I set the fan to AUTO high, both temp controls to the coldest setting, AC on, Recirc ON and vent control on any setting EXCEPT auto. IF you move the temp control off the lowest setting it gets warm or if you use AUTO vent it gets warm.

I wonder what is going to happen in the winter when it's not blowing hot enough :D :D

if you have the "recycle air" button on, it blows a lot harder

I pretty much keep mine in the auto setting. I have had no problems. It was in the 100's when I picked up the SRT and it handled the heat no problem. It has been in the 90's some days and the system cools things down quick. I will have to see how it goes in manual mode. My only complaint is the left vent on the driver side will not hold it's position.

heck yeah the AC sucks..!! the first day the heat wave shows up my AC decides to blow out warm air... fckin wonderful

you guys are P*ussies!! just roll the freakin window down geez!! hahahaha! no don't do that!! yeah, I was having the same issue and I think just recharging the system will take care of it!

I dont know about you guys, but I think it works just fine- I have only had the jeep since December, and I havent even used the recirc button yet....keep it on auto hi and autovent, set the gauge to 66 or wahtever, and it gets really cold.

I had my windows tinted from day one, and went last summer and yesterday it was hitting 98 and I had to regulate mine because it was real cold. Sorry I cant relate.
