Why is my AC pulley squealing?
A loud squeal is produced when the A/C is turned on. This symptom is usually caused by a loose or worn air conditioning compressor belt. This places a load on the engine and the drive belt that rotates the compressor. If the belt is loose or worn the belt can slip on the compressor pulley and emit a loud squeal.
Can you lubricate AC clutch?
Do not lubricate the clutch plates. If what you object to is the “click” that is simply the sound of the clutch being energized and pulling in. If it is happening constantly, you may have a low charge.
What causes a AC compressor to squeak?
If your air conditioning unit is emitting a high-pitched screeching or hissing sound, the most likely cause is high pressure built up in your compressor. If this is the case, the sound will most likely be heard outside at the unit when the AC first kicks on and will last about 10-15 seconds.
Can I spray wd40 on my AC clutch?
You could have a blown fuse or open circuit for the compressor. WD-40 will do nothing.

Why is my AC making a high pitch noise?
Most Common Reason: Low Return Airflow. In most cases, a high-pitched whistling sound means that your air conditioner isn’t getting enough airflow through the return vents and ductwork: the ones that pull air from your home to the air conditioning evaporator coils to cool it.
Why does my air conditioner clutch keep squealing?
This could either be the air conditioning clutch or the serpentine belt slipping. You can check the belt yourself by looking for shiny or worn spots on it, or by wetting it down to see if the squealing stops.
How do you remove a clutch from an AC compressor?
Remove the air conditioning accessory belt with the proper size wrench in your wrench set. Disconnect the connector on your compressor’s magnetic coil. Use the right size socket to remove the 6 mm bolt in the center of the AC clutch. Pull the clutch off, and observe the spacers on the shaft behind it.
Why is the outboard clutch on my AC not working?
Once an electrical current from the on/off switch sends power to the magnetic coil, it causes the outboard clutch to pull in toward the compressor, locking up the pulley and engaging the compressor. Because the clutch is attached to the compressor shaft, if it becomes disengaged, it will not move the compressor shaft.
What happens when the clutch on the Air Conditioner breaks?
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.
