How to Troubleshoot the Air Conditioning in a Mazda 6

by Editorial Team

Avoid a trip to the mechanic by trying to troubleshoot problems yourself in your Mazda 6. While air conditioning problems are common, they are often quite simple to diagnose and even fix. Take a few easy steps to try and determine the cause of the air conditioning problems on your own.

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

Get into the fuse box in a Mazda 6 from the interior of the car. Open the passenger side door and pry off the trim panel on the right side edge. Use the chart on the inside of the fuse box cover to find the right fuse. Pull out the fuse and replace it with a fuse of equal amperage.

Step 4

Disconnect the negative battery cable before getting to the control panel. Remove the center panel unit. Unscrew the four screws, one in each corner and pull out the climate control unit.

Step 5

Remove the blower motor if it is not properly working. After disconnecting the negative battery cable, drain the engine coolant into a container for reuse. Open the glove box door and remove the clips to pull the glove box out. Find the blower motor behind the glove box.
