Installed the fan and it fixed the issue, but fyi the dealer doesn't know anything about the resister, or how to order one if it ever fails. They don't have a pic of it on the system and there are no part numbers on it. It is a PW-115 resister though and google does have it as a fan speed controller. I ordered in the fan shroud since it says under item description fan shroud and solenoid but it is just the shroud.
