Avoid a trip to the mechanic by trying to troubleshoot problems yourself in your Nissan Maxima. Air conditioning problems are quite common, but can often be quite simple to diagnose and even fix. Take a few easy steps to try and determine the cause of the air conditioning problems.
Tools Used: Tools, Screwdriver
Troubleshoot Air Conditioning
Start the car and allow the engine to run for a few minutes.
Adjust the climate controls on the dashboard to make sure they are correctly working. If they are not working properly at all then the problem is probably in the control panel. If the controls seem to work but have no effect on the air pressure or temperature, then the problem is probably a blown fuse. If you cannot hear the accompanying blowing sound when adjusting the controls then it is probably a broken blower motor.
