What causes AC clutch to engage?
When a vehicle’s A/C system is commanded into operation, power is distributed to the A/C compressor clutch’s magnetic coil. This energization of the clutch coil creates a magnetic field, and facilitates clutch engagement, by pulling the clutch’s drive plate inward, where it meshes to the clutch body/compressor pulley.
Why is my AC compressor clutch not engaging?
What’s Preventing the A/C Compressor from Engaging? One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power.
Is the a / C clutch engaged all the time?
A/C clutch is engaged all the time, and low side pressure is at 250 psi with truck running high side 130 psi no cold air. Drained system and replaced orifice, vacuumed system down (low -27 high 0).
Why does the clutch engage but no cold air motor?
Since the clutch engages, there is enough refrigerant in the system (pressure) for the clutch to engage. If there wasn’t enough in the system, it wouldn’t even do that. If the system were where it is supposed to be, the compressor would kick on/off constantly once the system has been run for a little while.
What should the PSI be when the clutch is engaged?
Readings held for thirty minutes tried to charge with truck running and compressor clutch engaged was only able to get a little over half a can in system. With clutch engaged truck running low side is 95 psi and high side is 140 will not take anymore Freon. Help! have the same problem? Good morning.
