Symptom No. 1

  1. Turn ignition on. Check 30-amp power window fuse in fuse block, near left kick panel. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, measure voltage at Black/White wire terminal of main switch connector.
  2. If battery voltage is not present, repair Black/White wire between fuse and main switch. If battery voltage is present, disconnect main switch connector. Check continuity between ground and Black wire terminal of main switch connector. If continuity does not exist, repair Black wire between ground and main switch. If continuity exists, reconnect main switch connector and go to next step.
  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/Black wire (driver's switch in UP position)
    • Red/Green wire (driver's switch in DOWN position)
    • Green/White wire (main switch/passenger's in UP position)
    • Red/White wire (main switch/passenger's in DOWN position).
  4. Measure voltage at Red/Black wire terminal of driver's window motor connector with driver's switch in UP position. Also measure voltage at Red/Green wire terminal of driver's window motor connector with driver's switch in DOWN position. If battery voltage is not present at both terminals, repair wiring between main switch and window motor. If battery voltage is present at both terminals, check window motor, then proceed to next step. See WINDOW MOTOR TEST under COMPONENT TESTING.
  5. Measure voltage at Green/White wire terminal of sub-switch connector with main switch/passenger's in UP position. Also measure voltage at Red/White 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.
  6. 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.
  7. 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.
