I have a 2014 Mazda3. I love that car, but I've got one recent problem I haven't been able to fix. The AC "Auto" button is stuck down, and is off. I can't have the car control the air conditioning. Anyone else have this happen? Unfortunately, I think I'm out of warranty (over 60K miles already). I would hate to take this in to the dealer to get charged if someone knows a DIY fix for a stuck AC Auto button?
