Compressor Clutch Relay: Testing and Inspection
A/C Cut Relay
A/C Cut Relay Testing
The A/C cut relay does not set a trouble code in the on-board diagnostic system. It may be tested with an ohmmeter as follows:
Connector:
Resistance:
1-2
Infinite
3-4
Approx 120 Ohms
Apply 12V across relay terminals #3 and #4 and check that relay "clicks." With relay energized in this manner, resistance across terminals #1 and #2
should be 0 Ohms.
Replace the relay if it does not meet these specifications.
