What is the purpose of a clamping diode in an AC compressor clutch circuit?
The coil contains a clamping diode to prevent voltage spikes when the clutch suddenly disengages. It protects relay contacts and the control devices, such as the PCM, the BCM, or the ATC module.
How does the clutch work on an A / C compressor?
The A/C compressor clutch is a significant component of the A/C System. The A/C compressor itself is activated by an electronic clutch. As the A/C is switched on a drum inside the belt pulley is magnetized, this attracts and locks the belt drive in place so that it only adds resistance when engaged.
How much does it cost to replace an AC compressor clutch?
The AC compressor clutch replacement cost will be between $700 and $1000. Labor costs tend to be about $150 to $250, with the new compressor costing $450 to $850.
What should I do if my air conditioner clutch is spinning?
The clutch allows the compressor pulley to engage or disengage from the motor, ensuring it is only running when it should. If the clutch seizes, normal action cannot continue. Look at the front of the compressor while the air conditioning is running to see if the clutch is spinning.
What do you need to know about a / C compressors?
Built for trouble-free ownership and 100% visual and leak-tested, GM Original Equipment Compressors are engineered to match your original part in fit, form and function. The A/C compressor clutch is a significant component of the A/C System.
How does an air conditioner compressor clutch work?
When the A/C is switched off, the pulley on the A/C compressor spins freely. This frees up power and increases fuel economy when the A/C is not being used. When the A/C is activated, the compressor clutch transfers power from the engine’s crankshaft to the pulley mounted on the A/C compressor. How does an A/C Compressor Clutch Work?
Which is the best a / C compressor clutch for GM?
