How does the a / C CLUTCH relay coil work?

If the A/C cycling switch is closed (sufficient pressure), voltage is sent the PCM through circuit 347 (BK/YE). When the PCM receives voltage from the pressure switches, the PCM provides a ground for the A/C clutch relay through circuit 331 (PK/YE). The A/C clutch relay coil receives ignition voltage through circuit 391 (RD/YE).

Why does my AC keep tripping circuit breakers?

Still, there are steps you can take to troubleshoot an air conditioner that keeps tripping a circuit breaker: Replace your air filter – A restriction in airflow caused by a clogged air filter will force your cooling system to struggle, which often leads to overheating and potential breaker trips.

How is the compressor clutch relay turned on and off?

In some vehicles the compressor clutch relay is turned on and off by the low pressure switch and the evaporator temperature sensor. In a computer controlled system, the compressor clutch relay is grounded by the computer. If the fuse is good, disconnect the electrical connector from the compressor clutch coil.

What causes an AC compressor to not engage?

If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.

What causes an AC compressor fuse to burn out?

When a fuse burns out it is because the amperage draw exceeds the rating of the fuse. For an AC compressor protected by a 25 Amp fuse any amperage above this rating will burn out the fuse.

What should I do if my car fuse keeps blowing?

If the A.C. fuse on your car keeps blowing, I’ll start by stating do NOT install a larger fuse. The fuse is a protection device, and there is a problem in that particular circuit.

Why is my a / C system leaking all over the place?

The system shouldn’t be leaking out all over the place if it’s in operating order. The A/C system is supposed to be sealed, and if you overfill it…it won’t work either. You can try and bypass the pressure switch with a wire, if it turns the compressor on… well you have an issue with pressure (either the switch or too high or low pressure).

How can I tell if my AC compressor relay has failed?

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. While there are several reasons as to why an AC may stop producing cold air, a failed relay can be one of the most common.

How does the AC compressor relay work on a car?

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 clutch not working?

If your Air Conditioning compressor isn’t working (the clutch won’t engage) then watch this video. The A/C switch on the dash switches the compressor on, with one exception. If the PCM (powertrain control module) senses low pressure in the low pressure fluid line, it will stop the compressor clutch from engaging to prevent any damage.

What happens if your air conditioner compressor gets stuck?

The AC compressor is the most integral part of the air conditioning system which is responsible for pressurizing the refrigerant and its distribution. In case there is any problem with the AC compressor, your car’s AC will not deliver cold air and may even cause the engine to seize if the compressor gets stuck.

What to do if your a / C compressor won’t engage?

HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…

Why does my AC compressor clutch not engage?

Why AC clutch won’t engage If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways.

Check the front side of the clutch to examine its condition. Also, find out whether the clutch and the pulley are spinning. If only the pulley is rotating, the compressor clutch is having an issue, which could be stemming from several sources – a blown fuse, bad clutch oil, low-pressure lockout, or an open wire in the oil.

What should you do if your AC clutch is not engaging?

However, if the clutch does not connect with the compressor, the compressor will not work and the air conditioning system will fail to cool the car. Try checking if the clutch is in good condition by applying these steps: Turn the AC controls to maximum air conditioning.

What happens when the clutch on the Air Conditioner breaks?

However, it’s much more common for the clutch to break and make it impossible to turn on the air instead. Without the clutch, the compressor doesn’t receive any power from the engine, so you are left without air conditioning. When the compressor clutch breaks, the bearing inside the compressor can become damaged as well.

What should I do if my AC compressor clutch is not working?

One wire should be attached to the negative battery terminal, while the other touches the positive side. If your electromagnet is good, the compressor clutch will kick on. Remove the positive wire to release the clutch. You can repeat this process several times to ensure the clutch is working as it should.
