2000 Buick LeSabre a/c clutch will not engage. Fuse is good, can't tell if micro relay is ok or not, no power at compressor clutch plug when a/c is turned on. Are there other switches (full throttle...


There is a low refridgerant pressure switch, and a high refridgerant pressure switch. Either can cut the power to the clutch. You will have to check the pressure in the system to know for sure.
The electrical part in the clutch could be bad. You could run jumper wires to the clutch connector to see if it will engage. If not, its the clutch. If it does engage, then more than likely your just low on refridgerant, and possibly have a tiny leak.

Ac will blow warm air, the clutch does not engage. Could this be a compressor prob? Looked in the manual ...no trouble shooting ideas


Since you know that the clutch must engage in order for the compressor to operate, then there are most likely one of causes. The first is low or no freon in the system. The a/c system has a pressure sensor mounted in the low( return) side hose that prevents the clutch to engage if the freon is too low. The second would be the a/c fuse or relay faulty, preventing the clutch solenoid( a 12 volt electrically operated solenoid) from engaging. And the third would be that the clutch itself is bad because the solenoid wiring has broken. I suggest that first you locate the a/c clutch relay in the relay panel, remove the relay, carefully remove the plastic cover from the relay and reinstall the relay. The clutch should engage the compressor when you manually close the relay contact with your finger for one or two seconds. If the clutch does engage, your electrical circuit in ok and you are probably low on freon. A half of a can of r-134 in more that enough to operate the pressure switch. If it doesn't engage, check the a/c fuse or the clutch solenoid itself. Get back to me and let me know how things went. Dano

1997 Jeep Cherokee A/C clutch will not engage, even when i jumper out the low pressure switch.


as one of the steps to repair you might want to check the a/c cluth relay located in the Power Distribution Center. That is a box located behind the battery. Look for the right label on the inside of the PDC box cover. Check that that the relay is ok. If it is ok check voltage in the terminals that receive the relay (the terminals that power the relay coil) while the ignition key is in the on position and the a/c switch is on and the blower motor is on. If there is voltage there, then check for voltage in the terminal receiving the relay that powers the a/c clutch. If there is voltage there, Check for voltage in the cluch conector, if there is voltage there, then the clutch itself might be bad. If there is no voltage in the PDC terminals that energize the relay coil and/or the clutch, then the wiring should be checked, including the fuses.

Do not have power to a/c clutch what can cause this


If the fuse is OK, the the A/C relay is a very likely candidate. This can often be tested by swapping with an identical relay from another system. If the fault moves with the relay, the relay is the problem. If the relay is OK, the A/C switch is the next most likely cause.

Ok hear we go agian 2000 ford taurs 3.0 lit no a/c when i jump the compressor with a jumper wire. it works fine and i checked the high side swtich it works fine and the low side works ok to.


There are 3 likely problems:
  1. system could be air locked; when recharged, its possible more air than refrigerant was pumped into the system
  2. clogged or bad expansion valve
  3. AC clutch is bad; although it will engage when you jump it, the clutch could still be bad preventing it from engaging when you turn on the AC
Hope this answers your question. Best of luck.

I need a wiring diagram for the A/C system for my 98 XJ jeep, so that I can see if the ground wire that runs to the computer is cut or damaged. I have tested everything on the A/C system and the ground...


Biggest problem you will ruin into is that a schematic will tell you that a wire exists, but not where it is. Most times, you need to locate the wire and physically check it end to end...One note though; I have never seen a wire fail inside a harness unless from a short and burn. Most times damage, chafing or disconnect happens at the free ends and plug connections. Sure the relay is good?

Location Of Starter relay switch


sometimes its the simple things. On the foot pedal for the clutch are rubber grommets that push the switch in on the manual trans. they get old and fall off or develop holes in them so the switch does not get depressed.
