Troubleshooting Hints

1. Check POWER MIRRORS fuse. If open, repair circuit 1140 for a short to ground.
2. Check that G301 is clean and tight.
3. Each mirror motor contains an Electronic Circuit Breaker (ECB). ECB resistance increases if a motor is overloaded and returns to normal after voltage is removed from the motor terminals.
^ 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. Diagnostic Aids
^ Refer to Door. Doors, Hood and Trunk
^ Refer to System Diagnosis.
