Step 10 - Inspect Power Window Master Switch Circuit

WARNING: This page is about a different car, the 2002 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Exceptions: During 60 seconds after the ignition switch is turned ON to OFF (ACC) or until driver or a passenger's door is opened after the ignition switch is turned ON to OFF (ACC). If the circuit is not as specified, inspect the circuits connected to other parts.

Disconnect the connector from the master switch and inspect the connector on the wire harness side.
