Power Window Master Switch Input Test
NOTE:
Before testing, make sure the No. C8 (20 A), No. C9 (20 A), No. C10 (20 A), and No. C11 (20 A) fuses in the under-dash fuse/relay box are OK.
Before testing, make sure the No. D1-3 (50 A) fuse in the auxiliary under-dash fuse box is OK.
Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.

1.
Turn the vehicle to the OFF (LOCK) mode.

2.
Disconnect the power window master switch 24P connector

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.
