Power Window Master Switch Input Test

Note. The power window control unit is built into the power window master switch, and it only controls the driver's window operations.

Scheme 4

1. Remove the power window master switch (A).
2. Disconnect the 14P connector (B) from the master switch.
3. Inspect the connector and socket terminals to be sure they are all making good contact. If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system. If the terminals look OK, go to step 4 .
4. With the 14P connector still disconnected from the switch connector, make these input tests at the connector. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, go to step 5 . PROBLEM SYMPTOM TABLE Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 7 RED/YEL Connect the No. 11 and No. 7 terminals, and the No. 4 and No. 14 terminals. Check for driver's power window motor operation: It should run (the driver's window moves down). Blown No. 23 (20A) fuse in the under-dash fuse/relay box Faulty driver's power window motor An open or high resistance in the wire. 4 RED/BLK 3 BLU/RED Connect the No. 1 and No. 2 terminals, and the No. 3 and No. 10 terminals, then turn the ignition switch ON (II). Check for front passenger's power window motor operation: It should run (the front passenger's window moves down). Blown No. 22 (20A) fuse in the under-dash fuse/relay box Faulty power window relay Faulty front passenger's power window motor Faulty front passenger's power window switch An open or high resistance in the wire 1 BLU/WHT
5. Reconnect the 14P connector to the switch, and perform the following input tests. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, the control unit must be faulty; replace the power window master switch. PROBLEM SYMPTOM TABLE Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 10 BLK Under all conditions Measure voltage to ground: There should be less than 0.5 V. Poor ground (G501) An open in the wire 14 2 GRN/BLK Ignition switch ON (II) Measure voltage to ground: There should be battery voltage.

Blown No. 23 (20 A) fuse under-dash fuse/relay box An open in the wire 12 YEL/GRN Ignition switch ON (II) Measure voltage to ground: There should be battery voltage. Blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box An open in the wire 5 RED/WHT Ignition switch ON (II) Measure voltage to ground: There should be battery voltage. Faulty power window master switch Short to ground in the wire 6 LT GRN Under all conditions Measure voltage to ground: There should be less than 0.5 V. An open in the wire 13 BLU Ignition switch ON (II), and the driver's window switch in AUTO DOWN Measure voltage between the No. 13 and No. 14 terminals: There should be 0 V - about 5 V - 0 V - about 5 V repeatedly (a digital voltmeter reads about 2.5 V while the window moves). Faulty power window master switch Short to ground in the wire Faulty driver's power window motor 8 ORN Ignition switch ON (II), and the driver's window switch in AUTO DOWN Measure voltage between the No. 8 and No. 14 terminals: There should be 0 V-about 5 V - 0 V-about 5 V repeatedly (a digital voltmeter reads about 2.5 V while the window moves). NOTE: Do the power window control unit reset procedure (see «RESETTING THE POWER WINDOW CONTROL UNIT»(ref-290808-S20236797192008072200000) ).

Scheme 5

Scheme 6

1. Remove the driver's door panel (see «FRONT DOOR PANEL REMOVAL/INSTALLATION»(ref-290859-S33592132462008072200000) ).
2. Disconnect the 6P connector (A) from the driver's window motor.
3. Test the motor in each direction by connecting battery power and ground according to the table below. NOTE: To prevent damage to the motor, disconnect one lead as soon as the motor stops running.
4. If the motor does not run or fails to run smoothly, replace it.

Pulser Test

1. Reconnect the 6P connector to the window motor, and reconnect the 20P connector to the power window master switch.
2. Turn the ignition switch to ON(ll).
3. Measure voltage between the terminals at the driver's power window motor. There should be battery voltage between the No. 6 (+) and No. 4 (-) terminals when the ignition switch is turned ON (II). Connect an analog voltmeter between the No. 5 (+) and No. 4 (-) terminals, and run the window motor down or up. The voltmeter needle should move back and forth alternately between 0 V and about 5 V (a digital voltmeter should show about 2.5 V). Connect an analog voltmeter between the No. 3 (+) and No. 4 (-) terminals, and run the window motor down or up. The voltmeter needle should move back and forth alternately between 0 V and about 5 V (a digital voltmeter should show about 2.5 V).
4. If the voltage is not as specified, do the power window master switch input test at the appropriate terminals: No. 5, 6, 8, and 13. Refer to «Power Window Master Switch Input Test»(ref-290808-S26412192662008072200000)
5. If the switch is OK, replace the power window moter.
6. Reset the power window control unit. Refer to «Resetting the Power Window Control Unit»(ref-290808-S20236797192008072200000)

2. Disconnect the 2P connector (A) from the passenger's power window motor.
3. Test the motor in each direction by connecting battery power and ground according to the table below. NOTE: To prevent damage to the motor, disconnect one lead as soon as the motor stops running.
4. If the motor does not run or fails to run smoothly, replace it.

Scheme 11

1. Remove the switch panel (see «FRONT DOOR PANEL REMOVAL/INSTALLATION»(ref-290859-S33592132462008072200000) ).
2. Disconnect the 20P connector from the power window master switch.
3. Check for continuity between the terminals in each switch position according to the tables. Driver's Switch: The driver's switch is combined with the control unit so you cannot isolate the switch to test it. Instead, do «POWER WINDOW MASTER SWITCH INPUT TEST»(ref-290808-S26412192662008072200000) . If the tests are normal, the driver's switch must be faulty. NOTE: «RESETTING THE POWER WINDOW CONTROL UNIT»(ref-290808-S20236797192008072200000) if you disconnect the switch or replace it. Front Passenger's Switch
