Left Front Door Lock Switch Output Test
- Disconnect left front door lock switch connector. Measure voltage at left front door lock switch connector between Orange wire at terminal "B" (Aurora) or "H" (Riviera) and ground. If battery voltage is present, go to next step. If less than battery voltage is present, check rear fuse block instrument panel fuse No. 1. Also check Orange wire for an open circuit or short to ground.
- Connect a fused jumper between left front door lock switch connector Orange wire at terminal "B" (Aurora) or "H" (Riviera) and Light Blue wire at terminal "R" (Aurora) or "J" (Riviera). If all doors lock, go to next step. If no doors lock, check Light Blue wire for an open or short circuit to ground.
- Connect a fused jumper wire between left front door lock switch Orange wire at terminal "B" (Aurora) or "H" (Riviera) and White wire at terminal "S" (Aurora) or "K" (Riviera). If all doors unlock, check door lock switch connector for good terminal contact. If terminal contact is okay, replace door lock switch. If no doors unlock, check White wire for an open or short circuit to ground.
