Ac not working, air compressor clutch not engaging


Hi Adeyeri

Keep in mind that the Clutch won't engage for a few safety reasons.

Temperature inside vehicle
Temperature of compressor or pipes
Pressure inside pipes
Compressor jambed
Eg It's out of refrigerant Gas

You can momentarily engage the clutch by simply giving it +12v to the wire attached to clutch. Usually has a connector close by.
Or
If it has a Relay (click) in fuse box
You can by pass it with a jumper

A quick engage & disengage should allow you to detect possible problem.
But don't over ride the built in safety for more than about a minute.

Cheers
Hope this Helps

FIXED Car Compressor Clutch Won Engage

12 Volt Car Relays Used In Automotive Industry

1 Answer

No electrical power to AC Compressor. The switch light comes on in car when AC power button is turned on.


  1. Check if air blows with the fan setting turned to high.
  2. Check that the radiator cooling fan engages when the A/C button is pressed.
  3. Locate the compressor.
  4. Turn on the A/C.
  5. Check if the compressor's clutch has been engaged.
  6. If the clutch engages, the fault is elsewhere.
  7. If the clutch does not engage, check for power to the clutch.
These steps might help find the problem.

1) TEST the fuse+ relar of a/c
see the next steps and fix it. God bless you
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is locked up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged

Compressor clutch engaged with heat selected on 2004 silverado


Sounds like a problem with the selector switch or the HVAC control module, or the PCM.
The PCM thru the control module grounds the compressor relay when the compressor is needed.

I have 2002 Chevy s10 with ac issues. All blend doors and actuators work properly. Clutch engages on compressor. Blows warm air when ac is on. When I put a guage on it the psI stays on max and doesn't...


Yes. When you turn on the compressor via clutch Suction line pressures at around 3000 rpm should be around 30 PSI. If pressure stays high it is because the compressor is running but it is not doing squat and needs replacement - bad reed valves.

My 2002 neon's A/C blows warm air. The vent pressure is working well- but it blows warmer than the outside air. Can I fix this myself? What might the problem be?


If you are handy, yes you can. Most likely causes are loss of freon which would prevent the compressor clutch from being engaged and operating the compressor, a lack of 12 volts being applied to the compressor clutch because the a/c compressor fuse or relay has failed, preventing the clutch from engaging the compressor, or the compressor clutch itself failing. Easy test is to watch the compressor pulley with the motor running. The pulley will, of course be spinning, but the circular assembly mounted to the front of the pulley will spin with the pulley only when the compressor is engaged. There is a sensor mounted to the a/c line that prevents the clutch from engaging the compressor if there in not enough freon in the system. You could go to auto zone or checker and buy a can of freon r-134 with a hose for around $15.00. It is fairly easy to follow the instructions to charge the system. If, after allowing some of the can to pressurize the system, the compressor clutch engages then you can continue to charge the system. Cold air should start to blow by the time the can is empty. Or you can locate the a/c relay located in the fuse panel, remove its plastic cover and manually close the contacts while observing the compressor pulley assembly. If the clutch doesn't engage then the problem in probably electrical, a fuse, the relay or the electric clutch itself. Go to auto zone and check you their dvd on a/c repair for under $9.00. Hope this helps! Dano

Seems to have no power going to a.c. compressor


Compressor uses a clutch that is activated electrically by a relay. When you turn on the A/C, you should hear the clutch engage and pull power from the engine. If the clutch is not engaging, there may be several reasons:
wiring problem
HVAC switch failure
relay failure
compressor clutch failure
low refrigerant level

There is a sensor that checks the system return pressure and will not allow the clutch to engage if the refrigerant level is too low.

AC blowinghot air


Locate wires coming from compressor clutch and trace to nearest plug that you can unplug. Turn on A/C to max cooling. If clutch not engaged (center of compressor drive pulley not spinning with pulley), unplug compressor clutch wires and use multimeter to check voltage going to compressor clutch. If voltage is around 12 volts or more, then clutch should be engaged when plugged in. Plug clutch wires back in (with motor still running and ac set to max). If clutch still not engaged, then clutch definitely bad because 12V signal should engage it.
