my a/c is not cold anymore. i took it to firestone for a test and they say that the compressor and fan are working and it has freon. for some reason, there is 'no electricity' going to the compressor from the a/c on/off button. they also checked the fuses and relays and everything is fine. they can try to find where the 'short/electrical issue' is located but they'll charge more for that so i though i asked you guys first...any help would be appreciated.

TIA

lol compressor working with no electricity. If they say it has freon, then a quick test to be sure the compressor is still good, apply 12 volts to the clutch while monitoring the pressure ( if you have gauges) Also you could feel the lines with your hand and see if the temperature changes dramatically at any point along the line, not including the orifice tube or expansion valve which will be hot on one side and cold on the other. If you can get the pressure reading (while on) that will help a lot. pressure without a/c on and pressure with a/c on max
