How to Troubleshoot the Air Conditioning in a Mitsubishi Galant

by Editorial Team

Take a shot at trying to troubleshoot air conditioning problems in your Mitsubishi Galant before making a costly and time-consuming trip to the dealer or a mechanic. Sometimes air conditioning problems in an automobile can be an easy fix.

Step 1

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.

Step 2

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.

Step 3

Find the fuse box in a Mitsubishi Galant by opening the drivers side door and prying off the trim panel to the left of the steering wheel.

Step 4

Check the control panel next in your Mitsubishi Galant. If the air conditioning controls are not working at all, then the control panel is likely to blame. Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.

Step 5

Listen for the blower motor while adjusting the controls. Get to the blower motor in your Mitsubishi Galant by first disabling the airbags. Disconnect the negative battery cable. Remove the three instrument panel undercover mounting screws and remove the cover.

Step 6

Unplug and remove the compressor module. Detach the electrical connector from the fan motor, remove the three small bolts holding the motor to the housing and remove the motor and fan.
