All Power Windows Inoperative

  1. Check for blown P/WIND LH (20-amp) or P/WIND RH (20-amp) fuse, located in engine compartment fuse box. If fuses are okay, go to next step. If fuses are blown, locate and repair short to ground in power window circuit. See WIRING DIAGRAMS  . Replace fuse(s). Retest system.
  2. Turn ignition on. Verify battery voltage to fuse. If battery voltage exists, go to next step. If battery voltage does not exist, check battery condition and power feed to fuse box. Repair as necessary. Retest system.
  3. Turn ignition on. Using a voltmeter connected to ground, backprobe Pink/Blue and Pink wires at master power window switch. If battery voltage exists on both circuits, go to next step. If battery voltage does not exist on either circuit, repair open or short to ground in Pink/Blue wire to P/WIND LH fuse or in Pink wire to P/WIND RH fuse. Retest system.
  4. Turn ignition off. Using an ohmmeter connected to ground, backprobe Black wire at master power window switch. If continuity exists, replace master power window switch. If continuity does not exist, repair open in Black wire between master power window switch and chassis ground. Retest system.
