1999 Toyota Corolla Q&A
1999 Toyota Corolla Question: my car overheats when idling but only when the air is on.
if we turn the air conditioning off, the car cools back down, but if the air conditioning is on and we idle even for a few moments the car overheats terribly. we live in arizona so this is not acceptable. rented a toyota corolla and did not behave this way, what needs fixed? - allmartshopping
I would suspect an issue with the electric cooling fans - you didn't mention if the air conditioning also stops blowing cold air at idle? If the air is staying cold and the engine is running fine but the gauge is showing hot but not truly overheating, its possible you have a wiring issue with the gauge. - hav19
