Test C: A Single Power Window Is Inoperative - Passenger Power Window

PINPOINT TEST C: A SINGLE POWER WINDOW IS INOPERATIVE - PASSENGER POWER WINDOW

Normal Operation
Under normal operation, when the driver window control switch is commanding the passenger window up, voltage is sent from the driver window control switch to the passenger window control switch through circuit CPW13 (BN/YE) and ground through circuit CPW12 (GN/OG). When down is commanded, voltage and ground from the driver window control switch are reversed.

The passenger window control switch receives power through circuit CPW14 (VT/WH). Ground is provided by the driver window control switch (at rest) through circuits CPW13 (BN/YE) and CPW12 (GN/OG). When the passenger window control switch commands the passenger window up, voltage is sent to the passenger window control motor through circuit CPW20 (WH/OG) and ground through circuit CPW19 (VT). When down is commanded, voltage and ground from the passenger window control switch is reversed.

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