sonyman87 Posted May 7, 2005 Report Share Posted May 7, 2005 Ok. so i want to fix my AC that hasnt worked in over a year now. I took off the power connector to it and when ac is on with fans on and on cool setting i get ~.325volts and on Max ac i get ~.350 volts sorta fluxuates. well what are the voltages suppose to be to turn on the AC clutch? obiously if theres are way off, i need to find the relays and test them and since i cant find my chelton manual anywhere that will be sorta fun.

DiscoStudd Posted May 7, 2005 Report Share Posted May 7, 2005 The PCM won't activate the clutch if your system doesn't have a full charge of "gas." Might want to check the pressure first. Quote Link to comment Share on other sites More sharing options...

Might want to check the pressure first. i cant check or fill the charge when the pump clutch dosnt move... i aleady tried to fill it but the system wouldnt pump anything. no unusual noises from it at all so i dont think its engageing Quote Link to comment Share on other sites More sharing options...

sonyman87 Posted May 7, 2005 Author Report Share Posted May 7, 2005 holy crap 100 bux for a replacement clutch 200+ for remanufactured whole assembly and 350+ for oem Quote Link to comment Share on other sites More sharing options...
cutlsp Posted May 7, 2005 Report Share Posted May 7, 2005 yeah that was my reaction too that is why if the ac goes out i won't bother fixing it for a LOOOOONG time :oops: i may even end up bypassing the compressor during the winter to have more power Quote Link to comment Share on other sites More sharing options...

cutlsp Posted May 7, 2005 Report Share Posted May 7, 2005 i heard the um ac compressor can freeze up though and make it hard to start your car so i dunno :? Quote Link to comment Share on other sites More sharing options...
JoroCorona Posted May 7, 2005 Report Share Posted May 7, 2005 I'm pritty sure the AC clutch is ground controlled, so... why dont you just ground it out and let the car pull in the refridgerant? Just my .02 Quote Link to comment Share on other sites More sharing options...
jimmy91444 Posted May 7, 2005 Report Share Posted May 7, 2005 The compressor motor has to run while recharging your system. If it's not running your freon is low.This is what the book say's: ( The charging process requires the compressor to be running. Your compressor may cycle off if the pressure is low due to a low charge. If the clutch cycles off, you can pull the low pressure cycling switch plug from the evaporator inlet line and attach a jumper wire across the terminals.This will keep the compressor ON.) Then your freon or whatever should go in. Hope this help. Quote Link to comment Share on other sites More sharing options...
sonyman87 Posted May 7, 2005 Author Report Share Posted May 7, 2005 well i read somewhere on a chrysler AC that if the resistance across the plug i checked was suppose to be 2-3ohms. i got 4ohms and if it said if i had close to 5ohms of resistance then the electric clutch was fryed. I hope that isnt true for my car. The compressor motor has to run while recharging your system.

jimmy91444 Posted May 8, 2005 Report Share Posted May 8, 2005 Sorry i was away for the afternoon . I'm not sure but it should be on the low side.The book don't show a picture. Butt on my jimmy it's near the chrome canister and there is 2 wire, dark green and light green going to it. Can't see on the cutlass too much stuff on the way.
