One Power Window Inoperative

  1. If right door window is inoperative, go to step 6). If right door window operates, go to next step.
  2. Remove left door window switch. Leave switch connected to harness connector. Turn ignition switch to RUN position. Using test light, probe left door switch harness connector wire color and switch position indicated in LEFT WINDOW SWITCH FUNCTION TEST table. If test light illuminates on all indicated wires in corresponding switch position, go to next step. If test light does not illuminate on all indicated wires in corresponding switch position, replace left door window switch. Restore system to original configuration and retest.
    LEFT WINDOW SWITCH FUNCTION TEST

    Switch Position Wire Color
    Left Front Window UP White/Black
    Left Front Window DOWN Yellow
    Right Front Window UP White/Yellow
    Right Front Window DOWN Tan/Light Blue
    Left Rear Window UP Gray/Orange
    Left Rear Window DOWN Yellow/Light Blue
    Right Rear Window UP Red/Black
    Right Rear Window DOWN Yellow/Black
  3. Gain access to inoperative window motor and disconnect harness connector. See WINDOW MOTOR  under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using test light, probe suspect window motor harness connector using wire color and switch position indicated in WINDOW MOTOR CIRCUIT TEST table.

  6. Remove right door window switch. Turn ignition switch to RUN position. Using test light, check for voltage at right door window switch harness connector White/Yellow wire with left door right window switch in DOWN position. Check for voltage at right door window switch harness connector Tan/Light Blue wire with left door right window switch in UP position. Test light should illuminate in both tests. If test light illuminated in both tests, go to next step. If test light did not illuminate in both tests, repair open in circuit between left door right window switch and right door window switch harness connector. Restore system to original configuration and retest.
  7. Turn ignition switch to RUN position. Using voltmeter, check for voltage at right door window switch harness connector Light Blue/Black wire. Battery voltage should exist. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Light Blue/Black wire. See WIRING DIAGRAMS  . Restore system to original configuration and retest.
  8. Using test light, probe right door window switch harness connector Yellow/Red wire with right door window switch in UP position. Probe right door window switch harness connector Red/Yellow wire with right door window switch in DOWN position. See WIRING DIAGRAMS  . If test light illuminates in both tests, go to next step. If test light did not illuminate in both tests, replace right door window switch. Restore system to original configuration and retest.
  9. Access and disconnect right window motor harness connector. Using jumper wires, connect battery positive to one terminal of window motor connector. Momentarily connect remaining terminal of window motor connector to ground. Window motor should operate. Reverse jumper wires and repeat test. Window motor should operate in opposite direction. If window motor does not operate as described, replace window motor. Restore system to original configuration and retest. If window motor operates as described, repair open in Yellow/Red or Red/Yellow wire. Restore system to original configuration and retest.
