What are the symptoms of a bad AC relay?
No cold air. Another symptom that the AC relay has potentially failed is that there will be no cold air at all from the AC. If the relay fails, the compressor will not operate and the AC system will be unable to produce any cold air at all.
What is an AC compressor clutch and what does it do?
A car AC compressor clutch is used to connect and disconnect drive power to the car’s AC compressor shaft. Unlike a car’s transmission clutch, an AC compressor clutch is either transmitting full drive power to the AC compressor or not-it’s not supposed to provide partial power.

Why does my AC keep Tripping the circuit?
A “grounded compressor” or “compressor short to ground” means that an electrical winding inside the compressor has broken and hit the side of the compressor. This causes a direct short to ground, igniting the oil and causing a burnout. And, of course, the circuit breaker trips due to the sudden current surge.
Why does my air conditioner fuse keep blowing out?
If the compressor is not working properly, the air is not being cooled enough. This could be because of too-high levels of refrigerant in the AC, or as a result of frequently turning the machine off and then back on very quickly (within a minute of turning it off). The lifespan of a fuse can be up to 20 years.
