Why does my car overheat when idling and the air conditioner is on?
The car begans to overheat when idling and the air conditioner is on. Only one fan comes on but when I began to move the gauge goes back to below normal where it usually is. What could be causing this to happen? There is plenty of antifreeze in the car. Are both fans supposed be coming on when the car is started or at what point does both fans come on?

Lack of sufficient airflow across the radiator. Check to see if the secondary fan has power. If so, replace the secondary fan. If not, check the relays, fuse, and wiring.
The main fan only comes on when the engine reaches a certain temperature. The secondary fan is switched on when the AC is switched on, regardless of engine temp.
