Avoid a trip to the mechanic by trying to troubleshoot problems yourself in your Saturn Ion. While air conditioning problems are common, they are often quite simple to diagnose and even fix.
Tools Used: Tools, Screwdriver, Monkey wrench
Troubleshoot Air Conditioning
Start the car and turn the air conditioning on. Allow the engine to run a few minutes so the air can cool. Check to make sure you have the proper buttons selected. This simple step may uncover the root of the problem.
Adjust the climate controls. If they seem to work fine but have effect on the air, then the problem is probably a simple blown fuse. If the controls do not work correctly, then the problem is probably with the control panel. If you cannot hear the sound that accompanies turning the air from low to high, then the problem is likely with the blower motor.
