For those of you who have broken the gear for your recirculation, here is a how-to. The dealer wanted to charge $1,118 to fix total BS.
So, if you have found this laying around your passenger side floor somewhere, this is how to fix it......
Part #68072190AA - A/C & Heater Actuator Gear $18
Small Socket Wrench
First, you need to take the glovebox off. This was extremely easy. It isn't even held on by bolts. Here is a link to help you since explaining it would be hard....
Once the glove box is off, this is what you will see. The motor for the gear itself is held on by 3 T20 Torx bolts, one is hiding.
If you look closely, you can see the other gear in the middle of the picture. The piece you are fixing attached to this other gear to move the door.
Once you take the 3 torx screws off, you can hold the motor in your hand. The broken piece where the gear used to be held on pulls right off.
You can see the new part compared to the old part. They reinforced it, so there is no gap in between the plastic of the gear.
Take the new gear and slide it on the motor, but pay attention to how it goes on, because it has a very specific way of going on. It just slides on, that's it.
Now, I would say the trickiest part of this was putting the motor back into place. That circular part attached to the gear goes into a hole at a certain angle. This hole I'm referring to is the part that actually moves. I had to turn my recirculation on to get it to move into the right position in order to mount the motor back up. Once you get the gear into the hole, screw the torx bolts back in. Turn your car on and make sure the gear is moving properly by pressing the recirculation button on and off. If it is successful, put the glove box back on and you are good to go!
Congratulations, you just saved yourself $1100
Hope this helps!
