Regal V6-191 3.1L VIN M SFI (1995)
Heads Up Display Unit: Initial Inspection and Diagnostic Overview
Troubleshooting Hints
^
Check to make sure Head Up Display (HUD) window and windshield surfaces are clean and free of obstructions.
^
Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a
continuity/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 (refer to General
Troubleshooting Procedures). See: Diagrams/Diagnostic Aids
