AC pump clutch won't engage

I just had a transmission replaced on my 97 venture and now the air conditioner pump will not engage. All the fuses are ok. The wiring harness at the pump was disnonnected and reconnected. It still doesn't engage. I suspect a wiring problem as a result of the trasnmission change. Where should I look to fix the problem?

When you pull the plug off the ac accumulater take a short piece of wire and jump the two terminals . you should hear a click and see the compressor clutch engauge . if this is the case then the pressure switch is bad

They most likely did not refill the freon in the ac system.

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 ?

Air conditioner comes on comes out hot


the belt driven aircondisioning unit is located under the hood. there are usualy metal lines coming off of it and one should have a valve in it ...looks like a tire,air valve. when car is running, turn the AC on. the unit has a two part clutch that the belt will turn. when the AC is off...the pump or compressor will engage and the hole belt driven piece will rotate when the AC button is on. , when it is off....or not getting power to the clutch , the pully will spinn but the inside clutch will not.

iff the unit engages and turns when the AC is turned on, and still blows hot air, then you may have a leak in your refrigerant line. iff it dosnt engage, then check your fuses .if everything is good to go..then it is mostlikly a vacume issue located in the dash behind the AC switch and display that moves the vent from hot to cold....

Radio, lighter, and air conditioner on 92 buick le sabre malfunctioned...radio and lighter won't work at all, air conditioner won't recognize being turned on anything but defrost and defog. Could it be...


Check for a fuse that indicates radio and replace it if it's burnt through or melted or discolored. The Buicks have dash controls that require expensive repairs sometimes to get the temperature controls to work so some people jump around the controls by installing a separate toggle switch that directly turns the AC unit off and on for 92 through 94 Buicks. Any AC shop can install the bypass wires.

Ac clutch not engaging ac is blowing warm air but system is fully presurized on 02 venture van


pull connector off by evaporator can and cross a wire between the connector holes to close the circuit and this should keep the clutch engaged to let the freon go all the way through the system. If the vehicle was just reserviced the gauge will show full but it has not been pumped through the orifice tube area to the coil that cools your van interior. hope this helps.

AIR CONDITIONER QUIT WORKING


Pop the hood, start the vehicle and turn the AC on. Watch the compressor, it should have a center that rotates on an off and you should hear a clicking sound. This is the compressor clutch you are looking at. If the compressor is not doing this, check the fuses for the AC. If the fuses are good, then most likely the high side sensor switch is not working, therefore the clutch never engages and the air never gets cold.

Try that and get back to me, ok?

HI. Here is a complete check list that will help you trouble shot this issue. You will find the problem in one or more of these areas stated below.

1. Check Drive Belts - The air conditioner utilizes a drive belt that supplies power to rotate the compressor, which is basically a refrigerant pump. If the belt fails the compressor has nothing to drive it, inspect and replace as needed to restore operation. 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 system is low on refrigerant it could cycle on and off, making a ticking noise. If the compressor clutch is not turning proceed to next step.

3. Inspect for Refrigerant Leaks - If the system has a large leak and no refrigerant remains it will not activate. First test system for a static pressure charge, with the engine off attach an ac gauge to the low side pressure port and check the state of charge. Depending on outside temperature there should be between 50 psi and 80 psi. (Cool and warm). A refrigerant leak detector is needed to inspect for leak, but if you do not have a leak detector there is an alternative method. The air conditioner system is designed to run with oil suspended in the refrigerant to lubricate the system. Check for oily residue outside the system by inspecting all hoses, compressor, condenser, evaporator or receiver drier and replace any component that has failed.

4. Inspect Fuses - Check under dash panel and under hood power distribution center. Replace failed fuses as needed, recheck system. If the new fuse fails when reinstalled a short circuit is present and requires diagnosing with a wiring schematic, follow circuits to locate short, repair as needed and recheck system.

5. Check Temperature Control Vents - The vents inside your car are controlled by a cable, electrical servo or vacuum servo. If the temperature blend 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, insect for a vacuum leak or a shorted motor in the servo, repair the leak or replace the servo motor.
