My a/c compressor not working. I'm not getting any power to the clutch on the compressor.?

Question

all of my fuses are good.

Answer 1

Power goes from the switch to a relay. That may be the problem.Look in the fuse box, relays can be found there.

Answer 2

it depends on the car, but many have a safety switch. if the pressure of the refrigerant is too high or too low it will cut off the power

Answer 3

You're most likely low on refrigerant.  You weren't specific as to how old your car is.  There is a safety switch that monitors the amount of refrigerant there is in the system.  If low, it cuts off the compressor to prevent damage.  

You have to find out whether your system uses R12 or R134.  Somewhere under the hood there is a sticker that shows what refrigerant your car was equipped with.  It could be on the underside of the hood in a convenient reading position or along that structural rail across the front of the of the car and holds the radiator.  If there is no such sticker your system is most likely R12.  Also if your car was in an accident the sticker could have been obliterated.

If it is R134, you're in luck.  You can go down to your local auto parts store and get a recharge kit.  You locate the low pressure port, hook up the hose from the kit, open the valve and the gas goes in, relatively simple.  If you buy a recharge kit spend the little extra money and get one with a pressure gage.  You can plug it in and quickly check your refrigerant level even without a can of gas.

If it is R12 things get more complicated depending on what state you live in.  There are conversion kits to change your car from R12 to R134 but all of the old gas has to be gone.  And you're not supposed to dump it to the atmosphere because R12 eats the ozone layer.

Answer 4

connection back by fire wall

the compressor will not kick on if the freon level is low

check to see if you have power @switch

try going to auto zone they would check your problem and help free

have a nice day

Answer 5

Without the year, make and model it could be anything from a fuse, a relay, a fusible link, ecm problems, a shorted wire, a bad pressure switch, a bad a/c controller to just about anything....  

Answer 6

Year, make, model would be nice, but the clutch coil could be bad.

I know on my old 94 Ranger, I went without AC for about a year and a half because I got told the standard "You need to replace the compressor and blah, blah, blah..." when all I ended up needing was a $90 clutch coil and an hour of shop labor to get my AC running again.

Yay.
