I replaced one of my broken actuators because my AC only blew air to the defrost and heat vents. I messed up my AC Control module and bought a new unit and replaced it. I reset the system following the procedure i found online. It worked but sometimes it reverts back to just blowing air to the defrost and heat vents then i have to reset the system again. This usually happens if I change the direction of the air flow. Can someone help me figure this out? Thanks in advance.

 

Mt guess that your climate control unit is defective, so it reverts back to its original programming.

 

First, my advice is take it in to the dealer.



But if you need to work in it yourself, you'll need a set of AC gauges to know what's going on with the AC. Again, my advice is take it to the dealer.

 

I know this is an old thread but I am having the exact same problem. Any luck?
