Having problems with your 1999 Oldsmobile Aurora ?
Car gets hot
\015 Car overheats when sitting, but wont if air is on!!\015
Most of the time you can either unplug the fan switch and jump it with a paper clip to test it or ground one pin at a time on that plug to the engine and see if the fans come on. If so, then replace the switch or for a temp fix, just keep what ever you did together to make them come on when the key is on.
When the car reaches a preset temp the cooling fan is supposed to energize a realy the turns the cooling fan on....But if you turn the air on you basicly bypass the temp switch because you must have air moving at all times for the ac.. So now i would be looking for a defective temp switch or defective relay.....
