Troubleshooting Hints

Perform before beginning System Diagnosis
1. Check PWR ACCY Fuse 7 in I/P Fuse Block. If open, refer to Diagnostic Chart #5. Chart 5
2. If both mirrors are inoperative, check for poor connections at the Power Mirror Switch.
3. Check that G200 is clean and tight.
4. If only one mirror operates properly, check for poor connections at LH Outside Mirror or RH Outside Mirror.
^ Refer to Power and Ground Distribution for Outside Mirror replacement. Power and Ground Distribution
^ 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 "Diagnostic Aids/General Troubleshooting Procedures,"). Diagnostic Aids
