Test No. 3
- Turn ignition on. Measure voltage at Red/Black wire terminal of main switch connector with main switch/passenger's in UP position. Measure voltage at Green/Black wire terminal of main switch connector with main switch/passenger's in DOWN position. If battery voltage exists at both terminals with switch in indicated position, go to next step. If battery voltage does not exist at both terminals, check main switch. See MAIN SWITCH TEST under COMPONENT TESTS.
- Measure voltage at Red/Black wire terminal of sub-switch connector with main switch/passenger's in UP position. Measure voltage at Green/Black wire terminal of sub-switch connector with main switch/passenger's in DOWN position. If battery voltage exists at both terminals with switch in indicated position, go to next step. If battery voltage does not exist 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. Measure voltage at Green wire terminal of sub-switch connector with main switch/passenger's in DOWN position. If battery voltage does not exist at both terminals with switch in indicated position, check sub-switch. See SUB-SWITCH TEST under COMPONENT TESTS. If battery voltage exists at both terminals, go to next step.
- Measure voltage at Red wire terminal of passenger's window motor connector with main switch/passenger's in UP position. Measure voltage at Green wire terminal of passenger's window motor connector with main switch/passenger's in DOWN position. If battery voltage does not exist at both terminals with switch in indicated position, repair wiring between sub-switch and window motor. If battery voltage exists at both terminals, check window motor. See WINDOW MOTOR TEST under COMPONENT TESTS.
