Front Passenger's Power Window Switch Input Test
- Turn the ignition switch to LOCK (0).
- Open and close the driver's door, then carefully remove the front passenger's power window switch (see FRONT PASSENGER'S POWER WINDOW SWITCH REPLACEMENT ).
- Disconnect the 37P connector (A) from the front passenger's power window switch (B).
- 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 5.
- With the connector still disconnected, do 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, go to step 6.WIRE TEST CONDITION CHART
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 12 BLU Under all conditions, connect terminals No. 25 and No. 24 (or No. 12), and terminals No. 12 (or No. 24) and No. 37 with jumper wires. Check the front passenger's power window motor operation:
The front passenger's power window should open (or close).- Faulty front passenger's power window motor
- An open or high resistance in the wire
24 RED 29 BLU Disconnect the power window master switch 37P connector and moonroof control unit/motor 14P connector. Check for continuity between front passenger's power window switch 37P connector terminal No. 29 and power window master switch 37P connector terminal No. 27:
There should be continuity.An open in the UART wire Check for continuity between front passenger's power window switch 37P connector terminal No. 29 and moonroof control unit/motor 14P connector terminal No. 11:
There should be continuity.An open in the UART wire Check for continuity to ground:
There should be continuity.A short to ground in the UART wire
- Reconnect the connector to the front passenger's power window switch.
- Turn the ignition switch to ON (II), and do 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, replace the front passenger's power window switch (see FRONT PASSENGER'S POWER WINDOW SWITCH REPLACEMENT
).NOTE: After replacing the front passenger's power window switch. With the front passenger's power window AUTO UP/AUTO DOWN function, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).WIRE TEST CONDITION CHART
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 25 GRN Under all conditions Measure the voltage to ground:
There should be battery voltage.- Blown No. 13 (20 A) fuse in the passenger's under-dash fuse/relay box
- Faulty driver's under-dash fuse/relay box
- Faulty passenger's under-dash fuse/relay box
- An open or high resistance in the wire
37 BLK Under all conditions Measure the voltage to ground:
There should be less than 0.2 V.- Poor ground (G505)
- An open or high resistance in the ground wire
26 PUR Ignition switch ON (II) Measure the voltage to ground:
There should be battery voltage.- Faulty front passenger's power window switch
- A short to ground in the wire
27 PNK Ignition switch ON (II), and the front passenger's power window switch moving up or down Measure the voltage between terminals No. 27 and No. 37:
An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).- Faulty front passenger's power window switch
- Faulty front passenger's power window motor
- An open or high resistance in the wire
- A short to ground in the wire
28 ORN Ignition switch ON (II), and the front passenger's power window switch moving up or down Measure the voltage between terminals No. 28 and No. 37:
An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).- Faulty front passenger's power window switch
- Faulty front passenger's power window motor
- An open or high resistance in the wire
- A short to ground in the wire
36 BLK Under all conditions, disconnect the front passenger's power window motor 6P connector. Check for continuity to ground:
There should be continuity.- Poor ground (G505) or an open in the ground wire
- An open or high resistance in the wire
