I've checked into this over the summer and the dealer confirmed that in a 2010 GMC Terrain when you have the system in Recirculation mode -- No matter what the other settings are, -- that the A/C cycles on periodically because they were worried about moisture buildup.
I completely understand the AC cycling when I put it on defrost mode (Most cars I've ever had did that) but I can't understand why for Recirc?
Anyway, my question here is twofold.
1) when I first press the recirc button when I'm driving, there's a nasty smell that comes out that smells like I stepped in something. More than a moldy smell, or dirty sock smell, It smells like I'm driving by a refinery... I just had the air cabin filter replaced and I have observed water dripping from under the car after I've parked it, so I don't believe the filter is bad or the drain tube is blocked. Besides the other recommendations on this board to spray lysol inside the vents (not sure where the best spot to do that is, or if lysol affects leather or the rubber air vents?)
2) There was a section in the manual that I read that said not to use the Air Conditioning under a certain temperature or it can cause permanent damage to the compressor or Air Conditioning system. Now how would you suppose I do that if there's a bus that's driving in front of me blowing nasty black smoke, it's 10 degrees below zero and I put recirculation on? The AC compressor is going to cycle on to remove moisture from the inside of the car, and I don't want to have the AC system will break and then have to pay the dealer to fix it because I "turned the air on" during a cold day.
Btw - I did ask the dealer and they stated there is no way to disable the AC coming on when I put Recirculation on. I don't know of anyone else that wants to breathe bus fumes when driving, so please let me know what I can do for both of these questions!
Thanks.
