Diagnostic System Check - Lighting Systems

Many lighting malfunctions are attributed to the following conditions:
^ Loose connectors
^ Open or shorted wiring
^ Burned out bulbs
^ Bad switches
^ Inadequate ground
^ Blown fuses
Many of these conditions can be handled by replacing a defective part.

Reinstall all of the components after performing a special procedure (such as sealing washers). Repair any body sealing components that may of been disturbed, (such as grommets) in order for the passenger compartment to remain properly sealed.
