I believe that the fan(s) come on automatically with the AC system. Someone else might be able to confirm that. If so, then I would guess that you need to find and replace the temp sensor/switch for the fans.

What if your car is overheating when you turned on the air con?
It sounds like your cooling is not working when you turn on the a/c system...........

Coolant fan does not work and engine overheats on your 1993 saturn. Fan works when air conditioning is turned on?
You can check the cooling fan relay under the hood in the junction box but it would be a lot easier to just scan the vehicles computer......
Why is a cooling system required in a motor vehicle?
Because quite a lot of the energy used by a combustion engine gets turned into heat whether we want it or not, so a cooling system is needed to keep the engine from overheating.
2000 Chevy truck 5.3 engine runs hot when ac is turned on?
Maybe your cooling system needs to be flushed out.
Why does your air conditioner disburse an initial blast of warm air before cool air flows out?
It takes a moment for the cooling system to kick in and start cooling. So the warm air that is sitting in the system is forced out when the unit is turned on.
If you open your PC and look at the CPU how can you tell if it uses active or passive cooling?
If the PC and CPU are still plugged in and the computer is turned on, a person can tell if they have an active or passive cooling system. An active cooling system allows the fan to run constantly. A passive system allows the fan to run only when there is danger of overheating.
Kia pride overheats when AC is turned on.?
Answer: I think the aircon does not do anything with the overheat. vehicles are designed to run normal weather aircon is turned on or off. Check your engine's cooling system which comprised of raidiator, fan, fan motor relay switch and temperature switch. When cooling is not doing the job, you will not noticed this when you are running on the highway because your speed relative to the air cools the radiator. during traffic, no air is flowing so engine gets hotter and hotter. If you'll turn on your aircon, the time your engine overheats becomes shorter because the engine has increased its load. Kia's cooling system control is very simple. the circuit is composed of: 1. fuse 2. relay switch 3. temperature sensor switch 4. Fan motor which means you'll only have to check 4 components. When your aircon is on, radiator motor fan does not run continuously because it has a separate control. The load attributed by the aircon will be sensed by the temperature control and thus run the radiator fan but not continuously. Hope it helps
What causes heater not to get hot in 1999 gmc truck?
air pockets in the cooling system, start by bleeding the lines, plus there is a bypass for the heater core when you have the a/c turned on, or your heater isn't on, this fluctuate between makes and models. but i would go to youtube and look up how to bleed coolant lines, and that should make it easy for you.
What causes the water temperature to rise when the car is turned off after running?
A certain amount of the energy carried by the cooling water, is kinetic energy, from the circulation through the cooling system. When the engine is turned off, the water stops circulating. The kinetic energy contained in the water is converted to heat, thus raising the temperature of the coolant.
My 2002 Oldsmobile Intrigue continually overheats. Can someone tell me if it could be a sensor on this car and where it is located I have flushed the system changed thermostat and added coolant.?
Did you bleed all air out of the cooling system after the flush & refill? Trapped air can cause it to overheat. Remove the radiator cap and run the engine until no more air bubbles are escaping. Is the cooling fan working as it should? It should run continually when the A/C is turned on. There is a sensor that turns the cooling fan on when the engine reaches a set temperature. You may also have a blown head gasket or the water pump may not be pumping correctly. If you are loosing coolant with no apparent leak, there is a sweet smell at the exhaust, & bubbles coming from the radiator, you have a blown gasket.
Whirling noise under hood for 10 seconds after engine is turned off?
It is probably your cooling fans. These are electric and may run with the engine turned off. It is probably your cooling fans. These are electric and may run with the engine turned off.
