First thing to ask your self is, When you ingauge the clutch does cold air come out the vents? If so Charge is likely sufficent, If air is cool but not cold likely charge is low & is the cause of compresser not kickin on the clutch. place a proper charge in the system but make sure you know how much to add in, what type of refridgerant it takes ( 134-a ), (R-12). Besure that you use no sealers & that no sealers or Propane was used potentel system damage & injury or Death could result as improper proceeding at this point.
If you do have cold air check the lowside pressure switch function. You do this by first locating the switch disconecting the pigtail & useing a proper jumper wire across the 2 pigtail (female) ends of the harness connector not the switch its self.
If compresser clutch ingauges & Cold air blows from the vents replace low side pressure switch if this does not work grab your wallet,the yellow pages & the phone. I strongly recommend takeing your vehical to a qualified repair facility or Tech.
I Truely hope that I have helped your problem & Knowlege I have given you was useful!

Air conditioner


turn your key on and your air on and see if you have power to the compressor clutch, if yes needs new compressor, if no check pressure switch/ switches. usually screwed into accumulator. Make sure there is power to switch and then put jumper wire in plug to see if that kicks compressor in, if yes the get new switch if no power to switch trace wires and look for a rub/break in wire. if there is power and you jump switch and compressor still has no power to it then keep tracing wires. If harness is good check for power coming out of control panel in the dash. this is just basic troubleshooting, npt specific for your escort.

A/c does not turs on and off auto, it stais on at all times. high pressure switch and relay have been change. olso the switch inside the cab.


One of 2 things has happened here. Either the compressor clutch is seized to the pulley the belt rides on on the compressor OR the wiring for the clutch is shorted to a power supply. If the compressor clutch is stuck (seized to the pulley-usually with rust) on then the compressor will always turn with the engine. I have seen this several times over the years as I live in central new york where there is lost of rust on cars from salt on the highways in the winter. You can unplug the wire to the compressor and if it still spins with the engine running then it is siezed to the pulley. This WILL lead to compressor failure and WILL sieze the compressor due to overheating the compressor eventually. If the compressor does not spin with it unplugged and does when the wire is reconnected and doesnt stop ever while the car is running then it is shorted to a power supply somewhere. The Parasitic power problem can be hard to trace and is an unusual occurance. The clutch is probably locked up to the pulley but try my tests and you will know for sure.
Good luck and DO NOT try to unplug or replug in the compressor while the car is running.

I have a 02 lincoln ls . the air conditiong is not working . i took it to a local shop they check the compressor, fuses, relays, pressure swithches, all is checcking out good. They jump the compressor...


YOU COULD HAVE OPEN OR SHORT IN THE BLACK YELLOW WIRE GOING TO AC COMPRESSOR CYCLING PRESSURE SWITCH. CHECK FOR A SHORT OR OPEN IN RED YELLOW WIRES AT THE AC PRESSURE CUTOFF SWITCH. USE VOLT METER AND CHECK FOR VOLTAGE AT BOTH SWITCHES. PROBLEM COULD BE IN THE EATC MODULE THAT SEND POWER TO PURPLE WIRE THAT FEEDS THE AC PRESSURE CUTOFF SWITCH AND AC CLUTCH CYCLING PRESSURE SWITCH THEN FEEDS THE AC COMPRESSOR CLUTCH SOLENOID.

1986 chevy S10 has no power (12v) at fuse box on the fuse for ac clutch. checked both sides of fuse to ground 00v. ac/heater fuse 12v both sides (fan) works fine


hello, check all fuses, and relays, make sure wires to ac is not broke or has been pinched, sometimes you can run hot wire from battery, to compressor, touch hot side of plug in on comp wire see if it will kick on, if so sounds like a short, if compressor dont kick on with hot wire run to it, tap the out side of comp clutch and see if it kicks on, these compressors will not kick on any way if they are low on freon, once freon is full it should work.

When i turn the a/c on it blows the a/c clutch fuse


The ac compressor is probably siezed. When you're turning on the ac it cant turn the compressor so its blowing the fuse. It could also be that the clutch windings are shorted.

That would be my first guess.

You can locate the wires on the compressor clutch that engage the clutch, remove the belt, and leave the engine turned off. Apply power from the battery to the clutch wires and see if you can move it at all with your hands. Use small gauge wire and maybe put in a inline fuse. If the clutch is burned up it will blow the fuse. I think the inline fuses are pretty cheap at a auto parts store. If its not burned up, and you cant move the pulley at all by hand, more likely than not you need to replace the compressor.

Ac won't turn on?


Your compressor clutch is not engaged that was why AC is not on. The clutch is controlled by several sensors: coolant temp, refrigerant pressure, compressor speed sensor, evaporator temp sensor... First to make sure your Clutch is working then start tracing back to these other sensors. Look at the compressor, there is a plug of electrical wire on it. One prong is for speed sensor feedback, the others are for power connectors to turn on the clutch. Jump wires to power to clutch to check if it is working. That is just the beginning of AC troubleshooting. Good luck.

1999 Caddy Deville A/C problem


A/C systems are hard to diagnose without having access to the vehicle. One of the most common problems is undercharge (Not enough freon in the system) indicating a leak somewhere in the system. Other causes could be a burnt A/C compressor clutch fuse, defective compressor clutch, defective compressor/belt, defective High/Low pressure switches in the system, defective evaporator icing switch, defective wiring... Basically, you're better off getting the system diagnosed by a good A/C knowledgeable mechanic...

A?C does not work


Ford uses a relay system for the compressor clutch, have someone turn the a/c on while u listen for the relay to click. If you can hear it click check the compressor clutch wire (2 wire plug) to make sure it actually has power. the 6 and 10 series compressors that Ford uses are known to just fail all at once.
