When the vehicle is at idle, the AC will stop working properly. I do not have auto AC.. Basically the AC blower speed will slow down tremendously and the air will blow warm to cool and right after, the engine fan will kick on. It makes for an uncomftable ride during the summer here in Florida. Do you guys think something is wrong with the air or the engine is overheating? Ive taken it into mini and the first time, they said nothing was wrong. The second time, the check engine light came on and they replaced a thermostat sensor? (which should have corrected the problem), but now its acting up more. Thanks in advance!
