Power Window Master Switch Input Test
NOTE:
Before testing, make sure the No. A21 (20 A) fuse in the under-hood fuse/relay box is OK.
Before testing, make sure the No. B1 (7.5 A), No. B32 (20 A), No. B33 (20 A), No. B34 (20 A), and No. B35 (20 A) fuse in the under-dash fuse/relay box is OK.
Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.

1.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

2.
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 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 5.

Connect terminals No. 2 and No. 4, and terminals No. 1 and No. 3 with jumper wires.
Check driver's power window motor operation:
The driver's power window should close.
Faulty driver's power window motor
An open or high resistance in the wire
Connect terminals No. 1 and No. 4, and terminals No. 2 and No. 3 with jumper wires.
Check driver's power window motor operation:
The driver's power window should open.

LT BLU
Disconnect the front passenger's power window switch 37P connector and the moonroof control unit/motor 14P connector
Check for continuity between terminal No. 36 and front passenger's power window switch 37P connector terminal No. 34:
There should be continuity.
An open in the LIN (P/W) wire
Check for continuity between terminal No. 36 and moonroof control unit/motor 14P connector terminal No. 12:
There should be continuity.
An open in the LIN (P/W) wire
Check for continuity to ground:
There should be no continuity.
A short to ground in the LIN (P/W) wire

5.
Reconnect the connector, 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 power window master switch.

NOTE: After replacing the power window master switch, do the resetting the power window control unit.
