Having problems with your 1999 Saturn SL ?
I have a 1999 saturn SL and I'm having problems with it over heating when I have the air conditioner. It make noise when I shift in to another gear while the air conditioner is on. It sound like it's coming from the air condition.
You have most likely got troubles pertaining to the ac compressor and it`s components,a set of ac gauges would help diagnose the problem.
Yur transmission and your air conditioner are not in common. For your over heating problem check the engine coolant. Make sure the engine is cooled down prior to doing this. You will want to check the coolant levels in both the radiator and the over flow tank. The over flow tank will have marks indicating where the coolant levels should be when the engine is either hot or cold. Alot of engine noises will be heard through the vent ducting because they go to the engine compartment
