It can be many things. First make sure the cooling fan is running anytime the A/C is on. the cooling fan should run continuously with the A/C turned on. If not, either the fan motor or relay is bad. If that is not the problem, you need to service the cooling system, and see if the problem disappears. Start by cleaning the front of the radiator of all debris. Now drain the cooling system, flush the system with heater set to hot, and replace the thermostat with an exact match. Pour in a 50/50 mix of the correct Anti-Freeze and bleed all air from the system.

Your 2004 Grand Prix is overheated light on dash said to turn AC off Is the AC causing it to overheat?

Your AC should not cause your car to overheat. Your car probably has a different reason that it is overheating. However, your AC adds additional heat to the engine. Your car wants your AC off until you get the problem fixed. You would have a similar situation if you sprained your ankle while you carried your backpack. Someone would tell you to put down the backpack until you got your sprained ankle taken care of.

What cause cars to overheat with air conditioner on?

A car is more likely to overheat with the AC on because the AC radiator is in front of the cars radiator expelling heat. so if the engines cooling system is operating near capacity for some reason the heat coming from the AC can be just enough to tip it over the edge. The engine also has to work a Little harder while the Ac is running which would not help either.
