All Power Windows Inoperative

  1. Remove 20-amp power window circuit breaker from fuse block located below left side of dashboard. Check circuit breaker and replace as necessary. Turn ignition on. Using voltmeter, check voltage at circuit breaker input terminal on fuse block. Battery voltage should be present. If battery voltage is present, go to step 5). If battery voltage is not present, check power supply circuit for open, repair or replace as necessary. See . Restore system to original configuration and retest.
  2. Reinstall circuit breaker. Turn ignition switch to RUN position. Operate power window system. Reinspect circuit breaker. If circuit breaker failed, go to next step. If circuit breaker did not fail, go to step 5).
  3. Turn ignition off. Disconnect harness connector at left and right door window switches. See WINDOW SWITCH  under REMOVAL & INSTALLATION. Using ohmmeter, check resistance between ground and fuse block Light Blue/Black wire (power window feed circuit). If resistance is more than 5 ohms, go to next step. If resistance is less than 5 ohms, repair short to ground in Light Blue/Black wire between fuse block and window switches.
  4. Ensure ignition is off. Disconnect master window switch. Using ohmmeter, measure resistance between ground and master window switch harness connector Red/Yellow, Yellow/Red, White/Green, Tan/Light Blue, Red/Light Blue, Yellow/Light Blue, Gray/Orange, Yellow/Black and Red/Black wires. If resistance is more than 5 ohms, go to next step. If resistance is less than 5 ohms, repair short to ground in suspect wire. See WIRING DIAGRAMS  .
  5. Ensure ignition is off. Disconnect master window switch. Using ohmmeter, measure resistance between ground and master window switch harness connector Black wire. If resistance is less than 5 ohms, go to next step. If resistance more than 5 ohms, repair open in Black wire between master window switch harness connector and ground. See WIRING DIAGRAMS  .
  6. Ensure ignition is off. Remove master window switch from trim panel. Leave switch connected to harness connector. See WINDOW SWITCH  under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using voltmeter, measure voltage between ground and each wire color and switch position indicated in appropriate MASTER WINDOW SWITCH VOLTAGE TEST table. If all voltages are within specification, go to next step. If all voltages are not within specification, replace master window switch.

  7. Turn ignition switch to OFF position. Disconnect right door window switch. Turn ignition switch to RUN position. Using voltmeter, measure voltage between ground and right door window switch harness connector Light Blue/Black wire. If voltage is 10-14 volts, go to next step. If voltage is not 10-14 volts, repair open in Light Blue/Black wire between right door window switch harness connector and fuse block. See WIRING DIAGRAMS  .
  8. Turn ignition off. Reconnect master window switch. Remove right door window switch. Leave switch connected to harness connector. Turn ignition switch to RUN position. Using voltmeter, check voltage between ground and each wire color and switch position indicated in SINGLE WINDOW SWITCH VOLTAGE TEST table. If all voltages are within specification, go to next step. If all voltages are not within specification, replace right door window switch.

  9. Turn ignition off. Disconnect right door switch from harness connector. Disconnect right door window motor. Using ohmmeter, check resistance between right door switch connector White/Yellow wire and window motor harness connector Yellow/Red wire. Check resistance between right door switch connector Tan/Light Blue wire and window motor harness connector Red/Yellow wire. If resistance is less than 5 ohms, replace right door window motor. If resistance is more than 5 ohms, repair wire in question.
