Yes it can ,but if clutch not turning then run a direct feed from battery to check it first as it could be no gas,also to change it you will need to remove the compressor which will mean emptying the circuit with a special machine ,this gas is poisonous and must must be released into the atmosphere

Air conditioner will not blow cold air


Clutch on compressor needs replaced, possibly

1 Answer

I have a 1997 plymouth grand voyager. When I turn on my air conditioner, I do not receive any cold air only hot air.I used to receive cold out a couple of months ago but even then it would only blow c


The likely cause is a bad compressor clutch, but there are other possible causes. The first thing to do is to observe the compressor with the engine running. The clutch is inside the pulley. When the a/c is off, the pulley turns on thr belt, but the clutch does not turn. When the a/c is turned on, the clutch should lock on the pulley and turn with it. Run this test and post the result here.

Ac vent blower


proceed according 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

My GMC Sierra's air conditioning works great but the driver side vents will spontaneousely start blasting out hot air. The passenger side continuse to blow cold air. If iI turn the truck off and...


  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

2000 ford taurs a/c dont work it blows cold when i power up the compressor.its running 45 lbs on my gage on the low side.


Hi...
Perform the following basic Checks and Information
1. Check Drive Belts,If belt is intact proceed to the next step.
2. Check for Compressor Clutch Engagement - Turn the air conditioner to the "on" position and set controls to the coldest setting. Start the engine and allow to idle. Then open the hood and inspect the clutch at the front of the compressor, is it turning? "Engaged" if so, the system has enough refrigerant to activate. If the system is low on refrigerant it will not work properly. In this case an air conditioner recharge kit is needed to recharge the system. If the compressor clutch is not turning proceed to next step.
3. Inspect for Refrigerant Leaks
4. Check under dash panel and under hood power distribution center
5. Check Temperature Control Vents - The vents inside your car are controlled by a cable, electrical servo or vacuum servo. If the vent door is not functioning properly it will cause warm air from the heater to exit the vents. To check this start the car and allow the engine idle, next turn the blower motor speed on low, switch the temperature control from warm to cold while your ear is close to the vents. You should hear the door move inside the heater box as it swings from open to close. If not, inspect for a vacuum leak or a shorted motor in the servo, repair the leak or replace the servo motor.
Thanks

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold


check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning

I think the air compressor is bad in the truck


If your refrigerant level is OK and the truck blows cold air your compressor should be fine, in which case the noise is probably coming from the AC clutch which isn't too expensive or difficult to replace. If it doesn't blow cold air, switch the AC on and watch the compressor. If the clutch engages, but the compressor doesn't turn, the drive belt will squeal loudly and probably start to smoke. In that case it is the compressor which is expensive to replace. Most vehicles have an AC bypass that will temporarily cut out the compressor clutch under heavy load. If you are going uphill with the AC on or accelerating heavily you might notice warm air coming out of the vents for a short period until you let off the gas.
