AUTO-DOWN FEATURE INOPERATIVE
- Turn ignition on. Using voltmeter connected to ground, backprobe Blue/Red wire at master power window switch. See «WIRING DIAGRAMS»(ref-154662-S27928657442003052000000) . Completely depress left front control button, then release to activate auto-down mode. If battery voltage exists, go to next step. If battery voltage does not exist, or changes to zero volts before window is fully lowered, replace master power window switch. Retest system.
- Repeat step 1 while checking for battery voltage between Blue/Red wire and Blue/Yellow wire at master power window switch. If battery voltage exists, system is okay. If battery voltage does not exist, or changes to zero volts before window is fully lowered, replace master power window switch and retest system.
DRIVER-SIDE POWER WINDOW INOPERATIVE
- Turn ignition on. Using voltmeter connected to ground, backprobe Blue/Yellow wire at master power window switch while holding left front control button in UP position. If battery voltage exists, go to next step. If battery voltage does not exist, replace master power window switch. Retest system.
- Using voltmeter connected to ground, backprobe Blue/Red wire at master power window switch while holding left front control button in DOWN position. If battery voltage exists, go to next step. If battery voltage does not exist, replace master power window switch. Retest system.
- Using voltmeter connected to ground, backprobe Blue/Yellow wire at left front window motor connector with left front control button in UP position. If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short to ground in Blue/Yellow wire between master power window switch and left front window motor. Retest system.
- Using voltmeter connected to ground, backprobe Blue/Red wire at left front window motor connector with left front control button in DOWN position. If battery voltage exists, replace window motor. If battery voltage does not exist, repair open or short to ground in Blue/Red wire between master power window switch and left front window motor. Retest system.
MASTER POWER WINDOW SWITCH OPERATES DRIVER'S WINDOW ONLY
- Turn ignition on. Using a voltmeter connected to ground, backprobe and ensure battery voltage exists at specified wire color terminals of master power window switch while operating switch. See «WINDOW SWITCH POWER DISTRIBUTION»(ref-154662-S42547305402003052000000) table. See «WIRING DIAGRAMS»(ref-154662-S27928657442003052000000) . If battery voltage exists, go to next step. If battery voltage does not exist, replace master power window switch. Retest system.
- Using a voltmeter connected to ground, backprobe and ensure battery voltage exists at each passenger window switch while operating master switch. See «WINDOW SWITCH POWER DISTRIBUTION»(ref-154662-S42547305402003052000000) table. See «WIRING DIAGRAMS»(ref-154662-S27928657442003052000000) . If battery voltage does not exist, repair appropriate power feed circuit to passenger window switch. Retest system.

WINDOW SWITCH POWER DISTRIBUTION
MOTOR
- Turn ignition off. Disconnect window motor harness connector. Using fused jumper wires, connect battery voltage and ground to terminals of motor harness connector. Motor should run.
- Reverse leads. Motor should operate in opposite direction. If operation is not as specified, replace window motor.
MASTER POWER WINDOW SWITCH
Turn ignition switch to OFF position. Disconnect master power window switch harness connector. Using an ohmmeter, check for continuity between specified switch terminals while operating switch. See WIRING DIAGRAMS . If continuity is not as specified, replace master power window switch. Retest system.
PASSENGER POWER WINDOW SWITCH
Turn ignition off. Disconnect passenger power window switch harness connector. Using an ohmmeter, check for continuity between specified switch terminals while operating switch. See WIRING DIAGRAMS . Replace passenger power window switch if continuity is not as specified.
REAR POWER WINDOW SWITCHES
Turn ignition off. Disconnect appropriate rear power window switch harness connector. Using an ohmmeter, check for continuity between specified switch terminals while operating switch. See WIRING DIAGRAMS . Replace rear power window switch if continuity is not as specified.
