• Intermittent compressor cycling caused by relay contact wear
• Electrical switching problems in the A/C control circuit
• Relay failure related to heat, vibration, or moisture exposure
• HVAC system faults traced to a worn or incorrect relay specification

Installation Notes and Fitment Tips

Verify the vehicle’s relay cavity, connector style, and wiring diagram before installation.
