If Cooling fans work on my 1999 grand am why when it overheats don't they turn on?
The cooling fans turn on utilizing a temperature sensor and a relay. When the engine gets to a certain temperature the temp sensor closes and the cooling fans come on. Check fuses first. If you have a 12 volt test light, hook up the test light to the connector that goes to the cooling fans once the engine is warmed up and see if the light comes on. If it doesn't, the problem is in the power to the fans, check fuse, sensor and relay. If the light comes on and the fans don't, check for a proper ground (usually a green or black wire attached to a lug and bolted to the car chassis.

Why does the engine temperature rise when the car idles?
Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
