Why is the AC relay not working in my car?
We have pressure sensors in the car air-conditioning system that prevents the relay from energizing when the refrigerant is low. The most common cause of this situation is a slow leak from a Freon O-ring seal.
Why is my AC not working in my car?
The most common cause of this situation is a slow leak from a Freon O-ring seal. In rare cases, but likely on some models there may be a fault in the automotive computer system that prevents the control module from applying the ground to the proper leg of the air-conditioning relay. When this happens the relay won’t energize.
How do you test an AC compressor clutch relay?
In isolated situations where the AC compressor clutch relay has a unique part number we test it the old-fashioned way. Remove the component from the socket and test for a power signal and a good ground at the proper terminals.
What to do if your AC compressor is not working?
If you swap it out and the compressor is not kicking on you have a different problem. In isolated situations where the AC compressor clutch relay has a unique part number we test it the old-fashioned way. Remove the component from the socket and test for a power signal and a good ground at the proper terminals.
How can I tell if my AC relay has a problem?
AC compressor is not turning on. One of the most obvious signs that the AC relay may have a problem is that the compressor is not coming on at all. In most cases, when the AC is turned on you will be able to hear the compressor switch on.
What happens if the AC compressor relay goes out?
Without this relay, the AC compressor will not have power and the AC system will not function. The AC compressor relay is no different then other electrical relays – its electrical contacts will eventually wear or burn out, and the relay must be replaced.
What are the signs that your AC is not working?
Common signs include inconsistent cooling, not hearing a click from the compressor turning on, and no cold air. 1. Inconsistent cooling 2. AC compressor is not turning on 3. No cold air Almost every single electrical system on a car is powered through some kind of switch or electrical relay, and the AC system and compressor are no exception.
Why is my air conditioner contactor not working?
What could be the problem? Answer: If the contactor is not getting the 24 volts to the contactor coil then it could be a time delay relay (if the unit is equipped), thermostat problem, transformer problem, safety control, (low on refrigerate) wiring problem or a condensate pump, secondary drain pan safety switch problem.

What kind of AC relay does a jeep use?
Some of the most popular Jeep models ever made like the Jeep Grand Cherokee, Wrangler and Jeep Liberty all use an electrical relay with a high failure rate. In addition, these junk electrical components found their way into many Chrysler products like a decade’s worth of Chrysler Sebring and Dodge Avenger models.
