2002 Nissan Maxima Q&A
2002 Nissan Maxima Question: AC Turns off. Will come back on if manually restart.
My AC turns off (the RPMs also drop) usually at a stop light. Usually I can press Off and then Auto and it comes back. When it is on, the air is nice and cold. I just replace the cabin air filters since I had not done that for a while. This was happening before I did that though. Thanks - zandrew
Hello, Were you able to find out what was causing the problem with the A/C system? Thanks! - lawrenceg
Yes, it's possible. When the fan is not working, the A/C refrigerant (coolant) pressure increases to the point to where the pressure relief valve vents refrigerant to the atmosphere, thus causing the drop that you are experiencing. This doesn't mean that the system doesn't have a leak, which is fairly common under normal operation. I would get it recharged and make sure they add fluorescent dye in wiht the refrigerant, that way if it continues to leak, the shop will have a much easier time finding the source of the leak. - Bret Bodas
