The AC compressor turns off while the fan keeps running to circulate air and maintain ventilation in the room. This helps prevent the room from becoming stuffy or stagnant, even when the cooling function is not actively running.
Can't do it. The lubricant is mixed in with the refrigerant. Converted to air it would be running dry.
Could be your ac compressor is going or gone, probably gone.
The running refrigerator motor is using electrical energy to power the motor, which in turn drives the compressor to cool the refrigerator.
You have a cycling clutch compressor. Turn the AC on max, let the car for five minutes or so, go look at the compressor. You should see the clutch engaging and disengaging the compressor as the pressure builds and drops.
Under the hood, on the firewall you should be able to find a canister about the size of a tin can. There should be two tubes going into it and depending on the style there should be a sensor either connected to the canister or on one of the tubes. Turn on the AC with the engine running then jumper the two wires that go to the sensor on the canister. If the wiring is still intact and everything is functioning properly the AC compressor should turn on. If it doesn't engage the compressor clutch you may have a wiring problem. If the clutch engages but the compressor starts making bad sounds... well... you get the idea. Don't run it very long on the jumper. When the refrigerant leaks down that sensor keeps you from running the compressor without refrigerant pressure.
Running the AC compressor uses horsepower, and the truck does not have enough to overcome the loss.
If your EC light is on and will not turn off, it means you are probably low on refrigerant, R134a. The EC lights keeps the a/c compressor clutch off for 'economy' mode, helps save gas while your driving, but if you can not turn it off, its telling you the refrigerant is low and there maybe a leak.
If you want it constantly running jumper the high pressure cut off switch wire. And if you dont want it running turn off the ac. If pully is seized see if a napa can get a shorter belt to route around the ac compressor
If the clutch on the AC compressor has seized, the engine can in some situations stop running. The compressor could be bad but it is also possible that the clutch only is bad.
It might be that the A/C compressor isn't engaging when it is turned on? While the engine is running and while looking into the engine compartment at the compressor, have someone turn the A/C to the 'on' position and watch to see if the compressor actually engages or not. You ought to actually be able to hear an audible 'click,' and there will be a slight but noticeable change in the engine speed when it does. If not, then you might have a blown fuse or electric relay, or even a loose wire connection. It's also possible the that compressor may have failed.
Mabe your compressor clutch is no good. A good way to check it is to disconnect the wires that go to compressor then turn your ac on. If it does not burn the fuse it means your compressor clutch is bad.
If the A/C system is empty the compressor will not turn until you get enough refrigerant in it. Just turn on the A/C and hook up your can of freon. Once the freon starts filling the system the A/C clutch will engage.
