Test No. 1

  1. Check 30-amp POWER WINDOW fuse located in joint box, near left kick panel. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, go to next step.
  2. Remove driver's door trim panel. Turn ignition on. Measure voltage at Black/Red wire terminal of main switch connector. See WIRING DIAGRAMS  . If battery voltage is present, go to next step. If battery voltage is not present, repair Black/Red wire between fuse and main switch.
  3. Turn ignition off. Disconnect main switch connector. Check continuity between Black wire terminal of main switch connector and ground. See WIRING DIAGRAMS  . If continuity exists, reconnect main switch connector and go to next step. If continuity does not exist, repair Black wire between main switch and ground.
  4. Turn ignition on. Measure voltage at specified wire terminals of main switch connector with main switches in specified position. See POWER WINDOW MAIN SWITCH CIRCUIT TEST  . Refer to WIRING DIAGRAMS  . 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 TESTS.
  5. Remove passenger's and rear door trim panels. Measure voltage at specified wire terminals of each sub-switch connector with main switches in the specified position. Refer to POWER WINDOW SUB-SWITCH CIRCUIT TEST  . Refer to appropriate wiring diagram under WIRING DIAGRAMS  . If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, repair suspect wiring between main switch and sub-switch.
  6. Measure voltage at specified wire terminals of each sub-switch connector with main switches in specified position. Refer to POWER WINDOW SUB-SWITCH-TO-MOTOR VOLTAGE TEST  . Refer to appropriate wiring diagram under WIRING DIAGRAMS  . If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check sub-switch. See SUB-SWITCH TEST  under COMPONENT TESTS.

  7. Measure voltage at specified wire terminals of each window motor connector with main switches in specified position. Refer to POWER WINDOW MAIN SWITCH-TO-MOTOR CIRCUIT TEST  . Refer to appropriate wiring diagram under WIRING DIAGRAMS  . If battery voltage is present at all terminals, check window motor. See WINDOW MOTOR TEST  under COMPONENT TESTS. If battery voltage is not present at all terminals, repair suspect wiring between main switch and window motor (driver's window), or between sub-switch and window motor (except driver's window).
