Test B: A Single Power Window Is Inoperative - Driver Power Window

PINPOINT TEST B: A SINGLE POWER WINDOW IS INOPERATIVE - DRIVER POWER WINDOW

Normal Operation
Under normal operation, the driver window control switch is supplied voltage through circuit CPW30 (GY/YE). When the driver window control switch is commanding the driver window down, voltage is sent to the driver window motor through circuit CPW10 (YE/VT). Ground for the driver window motor is provided by the driver window control switch through circuit CPW11 (BU/GY). When up is commanded, voltage and ground from the driver window control switch is reversed.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Driver window control switch
- Driver window motor
- Smart junction box (SJB)
