Initial Inspection and Diagnostic Overview

1. Make sure ground G201 is clean and tight.
2. If Power Mirrors Switch does not illuminate when Park Lamps are turned "ON," refer to Interior Lights Dimming.

^ 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.
