Front Passenger's Power Window Switch Input Test
- Turn the ignition switch to LOCK (0), open and close the driver's door, then 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 4
- Reconnect the connector to the front passenger's power window switch, turn the ignition switch to ON (II), and do these input tests at the following 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
TROUBLESHOOT REFERENCE CHARTCavity 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 in the wire
37 BLK Under all conditions Measure the voltage to ground
There should be less than 0 5V- Poor ground(G505)
- An open in the wire
26 PUR Ignition switch ON (ID 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 front passenger's power window switch moving up or down Measure the voltage between terminals No 27 and No 37 An analog voltmeter should read about 0 V - about 5 V - 0 V - about 5 V repeatedly (a digital voltmeter should read about 2 5V while the window moves) - Faulty front passenger's power window switch
- Faulty front passenger's power window motor
- An open in the wire
- A short to ground in the wire
28 ORN Ignition switch ON (II), and front passenger's power window switch moving up or down Measure the voltage between terminals No 28 and No 37 An analog voltmeter should read about 0 V - about 5 V - 0 V - about 5 V repeatedly (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 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)
- An open in the wire
- Turn the ignition switch to LOCK (0), open and close the driver's door, then disconnect the 37P connector from the front passenger's power window switch again
- With the connector still disconnected, do these input tests at the following connector
- 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, then go to step 7
TROUBLESHOOT REFERENCE CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 12 BLU Under all conditions, connect No 25 and No 24 (or No 12) terminals, and No 12 (or No. 24) and No 37 terminals with jumper wires Check 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 in the wire
24 RED 29 BLU Under all conditions, disconnect the power window master switch 37P 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 wire - Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT )
