PW5: Check For Power Shorts To Ground
Turn the ignition key to the OFF position. Disconnect the interior fuse panel connector located behind the left hand side of I/P on left of the steering column. Disconnect the power main switch. Measure the resistance between the (Black/White) wire at the interior fuse panel connector and ground. See WIRING DIAGRAMS . Check the resistance, is it greater than 10,000 ohms? If yes, replace the power window main switch. If no, service the (Black/White) wire between the power window main switch and the interior fuse panel for short to ground.
