Normal Operation
Under normal operation, when the driver window control switch is commanding the driver window down, voltage is sent to the one-touch down (OTD) relay through circuit CPW10 (YE/VT). In the de-energized state, voltage is sent from the OTD relay to the driver window motor through circuit CPW01 (BN/BU). 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.

Possible Causes
- A short to voltage in circuit CPW10(YE/VT) or CPW11(BU/GY)
- A short to ground in circuit CPW01(BN/BU) or CPW11 (BU/GY)
- Smart junction box (SJB)
