Reasons Why the Car Compressor Does Not Rotate

[Talia]

Reasons why the car compressor does not rotate are as follows: 1. Severe internal wear of the compressor, leading to inability to function normally. The compressor plays a crucial role in the air conditioning system, primarily compressing and delivering cold air, which causes the compressor to operate in a high-speed rotating state for extended periods. 2. Check if there is any leakage in the refrigerant, as the compressor will not work without cold air to compress or deliver. 3. Faults in the electrical system are also a very common reason why the car air conditioning compressor fails to operate normally. You can check if the circuit is unobstructed and inspect the temperature sensor solenoid valve.

The old car I drove last summer had a problem with the compressor not working. It was extremely hot that day, and the air conditioning didn't cool at all, which caused me a lot of trouble. Later, I found out it was due to aging wires causing poor contact, a blown fuse, and possibly a faulty relay that made the compressor unresponsive. Normally, when driving, if you hear the belt squealing or the compressor making no sound at all, you should be careful. The compressor itself may also seize up, for example, due to long-term wear from using the air conditioning; or refrigerant leakage might trigger the system's low-pressure protection, preventing the compressor from starting. Now, during every maintenance check, I ask the mechanic to thoroughly inspect the electrical circuits to avoid issues, especially during hot weather when driving without air conditioning is unbearable.

With over a decade of driving experience, I've encountered many cases where the compressor wouldn't turn, mostly due to electrical issues. The most common problems are blown fuses from excessive current, failed relays that can't supply power to the compressor, or short circuits in circuits like the headlight switch, causing the entire system to fail. Mechanical jamming of the compressor or a loose belt can also prevent it from turning. If the compressor remains completely still after starting the car, remember to check the fuse box first; replacing a fuse is a small expense. Don't wait until the refrigerant leaks out, as that becomes more troublesome, costly, and time-consuming to fix. Pay attention to any unusual noises from the air conditioning system regularly; detecting potential issues early can save a lot of hassle.

Last month, my car's compressor suddenly stopped working, and the AC was blowing hot air, which was really uncomfortable. The mechanic said that in most cases, it's either a blown fuse or a faulty relay, and replacing them would fix the issue; poor wiring connections can also prevent current from passing through. It's less common but more troublesome if the compressor itself is old and seized or if the belt is broken. I was careless at the time, thinking it was a minor issue, but it dragged on until the refrigerant leaked. Fortunately, I got it repaired in time without delaying my car use. Such issues are really annoying in hot weather, so it's best to address them as soon as they're noticed.

That time on the highway when the compressor wasn't running and the AC had no cold air, the temperature inside the car skyrocketed instantly, affecting driving safety. The issue could be electrical: a blown fuse, relay failure, or a short circuit in the wiring; or it could be a mechanical problem like a slipped belt preventing the compressor from turning. When refrigerant is low, the low-pressure switch prevents startup to protect the system. After pulling over, I checked the fuse and managed to alleviate the issue somewhat. Regular maintenance can prevent these problems—don't wait for an emergency to act.

As a DIY car repair enthusiast, I often encounter situations where the compressor doesn't run, simply put, there's no power reaching the compressor. The reasons can be: 1) blown fuse or faulty relay; 2) broken wires or poor contact; 3) internal compressor failure or seizure; 4) loose or slipping belt. Too low voltage or refrigerant leakage can also trigger the protection mechanism. I usually start by checking the fuse box, then use a multimeter to test the circuit. Avoid modifications that affect voltage, otherwise the compressor is prone to damage. Timely maintenance of the AC system is crucial to avoid suffering on the road.
