Rear Power Window Switch

The battery voltage is supplied from the left front power window switch to the rear power window switches through CKT 1307 (DK BLU). For commercial vehicles (RPO V4U), the battery voltage is also supplied to terminal C of C312 and C319. When the UP switch is pressed, the voltage is applied to one terminal of the power window motor through the following circuits:
^ CKT 668 (DK BLU)
^ CKT 670 (DK BLU/WHT)

Ground is applied to the opposite terminal of the power window motor from the left front power window switch through the rear power window switch on either of the following locations:
^ CKT 169 (PPL) and CKT 669 (BRN)
^ CKT 171 (PPL) and CKT 671 (BRN)

When the DOWN switch is pressed, the voltage is applied to one terminal of the power window motor through either of the following circuits:
^ CKT 669 (BRN)
^ CKT 671 (BRN)

Ground is applied to the opposite terminal of the power window motor from the left front power window switch through the right front power window switch on either of the following locations:
^ CKT 168 (DK GRN) and CKT 668 (DK BLU)
^ CKT 170 (LT GRN) and CkT 670 (DK BLU/WHT)

For on-vehicle service, refer to the appropriate procedures.
