Bought this vehicle while ago, finally have time to deal with a/c. Previous owner said it was working, then parked for a while, than no work.
-display in vehicle stays on econ only
-checked clutch of compressor, couldnt rotate 360, had to force it to rotate, now goes 360 easily...
-when ignition on, very last connector at compressor gets 6 volts
-when disconnected, applied 12 volts, compressor clutch doesnt engage
-it is remanufactured Denso, looks fairly new
-pressure switch at condenser has 3 wires, one is ground, other two has 6 volts available...
-entire system needs to be charged, but dont want to waste refrigerant if compressor might be not working...

I have no wiring manual, didnt find any A/C fuses, dont know of location of relay, im fricking LOST.....
Thanks for help
aloha

Here's my theory, it's the same thing that's wrong with mine...

Evaporator is cracked and leaking = low pressure cutout switch = no compressor = no cooling.
