How does the rear AC work on a GMC Acadia?
Also, if you don’t have anyone sitting in the back rows, use the mimic functionality for the Aux unit. i.e. set the front unit to whatever you feel comfortable with and then cycle the Aux button off and on. This will bring the rear also in the same settings as front and will be pretty comfortable.
Why does the rear AC blow warm air?
I have heard of that issue on another acadia also. There are a few things you can do. Try turning the temperature control of rear system and see if it blows hot air when you turn it to full hot position. If that works, please reply back and there is a quick diagnosis that you can do to figure out the problem.
Why is my rear AC not turning off?
Today I disconnected both the front seat (near the shifter) and first rear seat controls for the rear AC. It didn’t change anything. I finally removed the fuse under the first rear seat to get it to stop blowing. Less than a year ago I replaced the front blower motor control module because the front speeds weren’t working right.
When does the rear AC blower turn on?
Three years ago I replaced the rear blower motor control module, which caused the rear AC to start working again. That was no fun with such a tight space to try to loosen and tighten nuts in! Since then there has always been, however, an approximate three minute delay for the rear AC blower to turn on.
Why is the air conditioning not working on my GMC Acadia?
There are many reasons why air conditioning may not be working properly on your GMC Acadia. When looking for the reason, you should always start with the most obvious cause, low refrigerant level in the system. In any case, it is advisable for laypersons to visit a workshop. In the event of a defect, the mechanic can directly initiate the repair.
