Problem with heating and air conditioning. The driver's side is blowing hot air and the passenger side is blowing cold air


Air Conditioner blows warm air
  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

Air conditioner isn't blowing cold air


Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to cool...now visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.

Air conditioner blows hot air fully charged with


compressor or receiver/dryer or condensor may need to be replaced. Further testing will have to be done. Look into your sight glass and see if there is any bubbles in the glass, or if glass is extremely foggy. If so, you may have air in the system. Check to make sure you are getting power to the compressor.

The air conditioner switches off


If you are positive it is full, then I would have someone check the pressure switch on the evaporator. When the system pressure drops, it will shut off the system. Usually people think the system does not work when I buy a car, and 9 out of 10 times it is just not fully charged. I wish you luck and have a great day.

Why do they want to replace the compressor?noisy?If you can put a charge on the ac then it's hot again after a day,then you have a leak.all the ac lines have o-rings where they are connected.without put dye in the system you wont know for sure.So I would try that first.
