Test B: Single Power Window Inoperative (4-Door)
- Turn ignition switch to RUN position. If driver's power window control switch LED(s) illuminate, go to next step. If driver's power window control switch LED(s) do not illuminate, go to step 9
.
- Turn ignition switch to LOCK position. Remove driver's power window control switch. See POWER WINDOW CONTROL SWITCH
under REMOVAL & INSTALLATION. Test driver's window control switch. See DRIVER'S POWER WINDOW CONTROL SWITCH (2-DOOR)
or DRIVER'S POWER WINDOW CONTROL SWITCH (4-DOOR)
under COMPONENT TESTS. If driver's power window control switch is okay, go to next step. If driver's power window control switch is faulty, replace driver's power window control switch and retest system operation.
- Connect driver's power window control switch harness connector. Remove power window control switch at inoperative window. See POWER WINDOW CONTROL SWITCH
under REMOVAL & INSTALLATION. Test power window control switch. See PASSENGER'S POWER WINDOW CONTROL SWITCH
under COMPONENT TESTS. If power window control switch is okay, go to next step. If power window control switch is faulty, replace power window control switch and retest system operation.
- Disconnect inoperative power window door harness connector located in respective door's "A" or "B" pillar. Measure voltage in inoperative power window door harness connector terminal between driver's connector C41 terminal No. 9 (Green/Blue wire), passenger's connector C43 terminal No. 9 (Green/White wire), right rear connector C46 terminal No. 7 (Green/Yellow wire), or left rear connector C45 terminal No. 7 (Green/Red wire) and ground. See Fig 1
or Fig 2
. If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair open or short in appropriate wire and retest system operation.
- Connect power window control switch harness connector at inoperative window. Operate inoperative power window control switch in DOWN and NEUTRAL positions. Measure resistance in inoperative power window door harness connector terminal between driver's connector C41 terminal No. 9 (Green/Blue wire), passenger's connector C43 terminal No. 5 (Yellow/Violet wire), right rear connector C46 terminal No. 2 (Yellow wire), or left rear connector C45 terminal No. 2 (Yellow/Blue wire) and ground while operating inoperative power window control switch in DOWN and NEUTRAL positions. If resistance is less than 5 ohms in DOWN position and greater than 10 k/ohms in NEUTRAL position, go to step 7
. If resistance is greater than 5 ohms in DOWN position or less than 10 k/ohms in NEUTRAL position, repair open or short in appropriate wire and retest system operation.
- Operate inoperative power window control switch in UP and NEUTRAL positions. Measure resistance in inoperative power window door harness connector terminal between driver's connector C41 terminal No. 9 (Green/Blue wire), passenger's connector C43 terminal No. 11 (White/Violet wire), right rear connector C46 terminal No. 4 (White wire), or left rear connector C45 terminal No. 4 (White/Blue wire) and ground while operating inoperative power window control switch in DOWN and NEUTRAL positions. If resistance is less than 5 ohms in DOWN position and greater than 10 k/ohms in NEUTRAL position, go to next step. If resistance is greater than 5 ohms in DOWN position and less than 10 k/ohms in NEUTRAL position, repair short to ground in appropriate wire and retest system operation.
- Disconnect inoperative power window motor harness connector. Operate inoperative power window control switch in DOWN position. Measure resistance in inoperative power window motor harness connector between driver's connector C782 (White wire), passenger's connector C783 (White/Violet wire), right rear connector C785 (White/Red wire), or left rear connector C45 (White/Blue wire) and ground while operating inoperative power window control switch in DOWN position. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair short to ground in appropriate wire and retest system operation.
- Operate inoperative power window control switch in UP position. Measure resistance in inoperative power window motor harness connector terminal between driver's connector C782 (Yellow wire), passenger's connector C783 (Yellow/Violet wire), right rear connector C785 (Yellow/Red wire), or left rear connector C784 (Yellow/Red wire) and ground while operating inoperative power window control switch in UP position. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair short to ground in appropriate wire and retest system operation.
- Turn ignition switch to LOCK position. Disconnect inoperative power window control switch harness connector. Turn ignition switch to RUN position. Measure resistance in inoperative power window control switch harness connector terminals between driver's connector C486 terminal No. 3 (Black wire) and terminal No. 4 (Green/Blue wire), passenger's connector C489 terminal No. 4 (Black wire) and terminal No. 2 (Green/White wire), right rear connector C491 terminal No. 4 (Black wire) and terminal No. 2 (Green/Red wire), or left rear connector C490 terminal No. 4 (Black wire) and terminal No. 2 (Green/Red wire). See Figure
or Fig 3
. If voltage is greater than 10 volts, replace inoperative switch and retest system operation. If voltage is less than 10 volts, repair open in appropriate wire and retest system operation.
