Troubleshooting Hints - Interior Lights Dimming

START DIAGNOSTICS HERE
Perform the checks listed below before performing System Diagnosis.

1. Make sure Park Lamps turn "ON" and "OFF" normally before proceeding with diagnosis.

2. Check ground G200 by noting normal operation of the Blower Motor.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity or voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
