Troubleshooting Hints - Interior Lights

PERFORM THESE STEPS FIRST


1. Check RDO1/AUX Fuse by noting operation of the Radio.

2. Check CTSY Fuse and AUX Fuse.

3. If all Courtesy Lamps remain on at all times, disconnect each Jamb Switch until the Courtesy Lamps turn "OFF." Replace the defective switch. If Courtesy Lamps remain "ON" after all Jamb Switches are disconnected, repair short to ground in CKT 156.

^ 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.

^ Refer to the Symptom Table for appropriate diagnostic procedures.
