When i bought this car the ac wasnt working, so i dont know what happened when it went out. The compressor just wont kick on. It has no power going to it. I checked the switch, and tried bypassing it and still nothing. I checked both fuses, 1 by the driver door and one under the hood. I also checked the relay under the hood on the passenger side, and that seems to be good. Somebody told me sentras have another relay that turns it on somewhere. I checked the clutch and it spins, so im pretty sure thats good. I checked the pressure, but i dont think that will tell us anything because the compressor has never kicked on for me. But the low side is high and the high side is low. Im baffled, any info will help, FL is hot and i would love AC!!! Thanks Guys!
