Symptom No. 3
- Turn ignition on. Measure voltage at the following wire terminals of main switch connector with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check main switch. See MAIN SWITCH TEST under COMPONENT TESTING.
- Red wire (driver's switch in UP position)
- Green wire (driver's switch in DOWN position)
- Black/White wire (main switch/passenger's in UP position)
- Black/Yellow wire (main switch/passenger's in DOWN position).
- Measure voltage at Black/White wire terminal of sub-switch connector with main switch/passenger's in UP position. Also measure voltage at Black/Yellow wire terminal of sub-switch connector with main switch/passenger's in DOWN position. If battery voltage is present at both terminals, go to next step. If battery voltage is not present at both terminals, repair wiring between main switch and sub-switch.
- Measure voltage at Red wire terminal of sub-switch connector with main switch/passenger's in UP position. Also measure voltage at Green wire terminal of sub-switch connector with main switch/passenger's in DOWN position. If battery voltage is present at both terminals, go to next step. If battery voltage is not present at both terminals, check sub-switch. See SUB-SWITCH TEST under COMPONENT TESTING.
- Measure voltage at Red wire terminal of passenger's window motor connector with main switch/passenger's in UP position. Also measure voltage at Green wire terminal of passenger's window motor connector with main switch/passenger's in DOWN position. If battery voltage is present at both terminals, check window motor. See WINDOW MOTOR TEST under COMPONENT TESTING. If battery voltage is not present at both terminals, repair wiring between sub-switch and window motor.
