Question about 1998 Ford Mustang
When Idling the air conditioning gets warm and the car starts to overheat. When I start to drive the air gets cold again. Heat works like crazy no problem at all except I live in FLORIDA! I also noticed that when I popped the hood to check the radiator coolant level that the fan was not running to the radiator. Does it kick on and off as needed or is it supposed to run continously with the air on? Anyone know what the problem could be? I'm getting ready to go on a trip and am desperate to get this fixed asap.
Take a look through your front grill and see if there is alot of bugs,dirt,etc. blocking the cooling fins of the condensor and radiator. If so try rinsing them with a water hose, or air pressure. Some cleaners work well also,like " Simple Green " or gunk degreaser. Catch the fluid in a container and dispose of properly.

On a stock mustang, the electric cooling fan runs at 2 speeds, the low speed turns on and off at certain coolant temps, the high speed turns on when the engine is hot and the air conditioning is on. I believe the fan should turn on automatically if the a/c is on. The fan is controlled by the pcm and the fan speeds are controlled by the constant control relay module (ccrm). basic things to check are the fuses, make sure the fan motor is good, and of course the ccrm. on a 98 the ccrm is located in the right fenderwell. good luck, my 96 cobra starts to overheat with the a/c on, getting ready to change the factory radiator with a high performance one. hopefully that should fix that.

Sounds like the front of the radiator or A/C condenser is clogged up...take a water hose and try to clean any debre from the front, so air can pass freely...
