Why does my air conditioner not work when idling?
When idling, AC does not work and engine overheats. What’s the cause? I drive a 2013 Chevy Sonic. Basically, the air conditioning does not blow cold air if the car is idling, only when in motion. It seems to blow the coldest during long periods of driving fast, such as on the freeway.
