Troubleshooting Hints - Compressor Controls

1. Check A/C Clutch Fuse for an open.
2. Make sure A/C Compressor Clutch and A/C Clutch Relay connectors terminals are free from corrosion.
3. Make sure grounds G109 and G201 are clean and tight.
4. Make sure A/C System has proper refrigerant level. Check for leaks, etc.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
