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.
