Nissan Repair: 2000 Maxima Air Conditioning, refrigerant r134, pressure switch
QuestionAC always blows very cold. Yesterday a little too cold. I slid the temp over about 3/4 an inch. Worked fine. This morning warm air. Fuses all ok. I don't think the compressor is kicking in. Any ideas?
AnswerAlan,
You will need to perform a systems check on the pressures. If you have a set of gauges to check what is going on. My bet is the pressure cycling switch is defective and there is not a blockage or the system is low on refrigerant (R134). The pressure switch is under $50 bucks. Try to rund the system on Max, recycle and see what happens as the control for temperature could be defective. These are usually bulletproof so I think it would be the pressure switch as my first thought.
