Compressor Clutch: Service and Repair

Clutch Break-in
After a new clutch has been installed, check the voltage and amperage to the clutch (determine it to be satisfactory). Then cycle the A/C clutch approximately 20 times (5 sec. on and 5 sec. off). For this procedure, set the system to the A/C mode, using high blower, and engine rpm at 1500-2000. This procedure (burnishing) will seat the opposing friction surfaces and provide a higher clutch torque capability.
