Nissan Repair: 1994 Nissan Quest AC, nissan quest, valve problems

Question
The AC doesn't power on. It was repaced by the dealer 3 years ago. Is there a fuse for the AC under the hood? I checked the gas charge level and it is fine. What else could be the problem? Thanks

Answer
Derek,

First check to see if the compressor is activating the clutch when the AC is on.  If it is then you have expansion valve problems and that is what is causing the system not to cool.  If the inside blower is not working I would be looking at the resistor cluster or the master switch.  There is an AC relay and a fuse.  On yours I think it is under the hood on the driver side.
