    May be a pressure switch bad. Hvac techs only know how to change filters,blower, condensor motors and add freon on household and commercial units. The pressure switch will transmit power to the clutch. You have a high and low pressure switch. Check for power output.

97 chevy suburban AC clutch won't engage pressures


Looks like the low pressure switch gets power from a 10amp ac fuse. Power then goes to the ac relay which is powered on by the ac heat controller on the dash. Power then goes thru the high pressure switch to the compressor. The ac relay is grounded to the body. Do you have power on the lite and dark green wires going into the relay and is it grounded ?

No power to a/c compressor, I have checked the fuses, relays and freon.


The trigger from the dash switch activates the relay which in turn switches on the solenoid pulley to engage the compressor to work. If this circuit is traced the fault of a open circuit can be found out. If there is no power in the fuse or relay then the main wiring must be checked.
Also a failure of the solenoid clutch cannot engage the compressor and so the circuit to this section must be checked.

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

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.

1996 Lincoln Town Car. The A/C compressor will not engage. Freon is not an issue because I have by-passed the low pressure cycle switch. The control in the car is on "max ac". I have also replaced the A/C...


Is the solenoid clutch holding on to engage the compressor, if not the relay or the fuse or the sitch is not active. check the connection to the relay.
If solenoid is turning the compressor then there is no pumping and so the cooling does not happen.It can be failure within the compressor, needs an overhauling .

A/c has full freon but the compressor clutch wont engage. i have found that the plug going into the compressor is not getting any power. what could be the problem?


On the low pressure line of the ac you have a pressure switch which allows the compressor to come on once a certain pressure is reached, and it will cut the compressor off if the pressure is too high or too low. Look at your ac hose and find the switch *you will see wires connected to it* you may need to replace this switch. You can use a test light to see if you are getting power to the switch. You should check you fuses, and the ac relay witch is usually in a black plastic box under the hood.
