Air conditioning problems are too common in many autos, especially in older models like Mitsubishi 3000GT which are no longer made. Save money by doing this yourself and avoiding a trip to a mechanic to have this problem checked out.

Troubleshoot Air Conditioning
Start the engine and let it to run for a few minutes to allow the air to cool. Double check the controls to make sure the correct buttons are selected. This may seem simplistic, but human error could be to blame.
Adjust the climate controls. If the climate controls do not feel right, then the problem is probably in the control panel. If the controls feel fine, but have no effect on the air then it is probably a blown fuse. If you cannot hear the accompanying blowing sound when the air is turned from low to high, then the problem is in the blower motor.
