Front Cross-Over Harness 2. Feed Harness to Rear Door o r Quarter Window 3. & 4. Left and Right Rear Door o r Quarter Window Harnesses Front Cross-Over Harness This harness is installed beneath the instrument panel and completes the circuit from the right door Fig. 1 1-1 -Front End Power Window Wiring to the left door windows on all styles except on Cadillac styles. (See Figs. 11-1, 11-2, 11-3, 11-4 and 11-6). On Cadillac styles the cross-over harness is installed on the floor pan - see Figure 11-5. Feed Harness for Rear Doors or Quarter Windows This harness of flat wire construction connects to the front cross-over harness on the left side of the shroud (fire wall) and extends rearward under the flat body wire harness. In two door 'styles the quarter window harness divides a t the r e a r of the r e a r seat on all styles except Cadillac styles, s e e Figures 11-7, 11-8, 11-9, 11-10, 11-11, 11-12, 11-13 and 11-14. - Chevrolet "B" Fig. 1 1-2-Front A.

To disengage the connector, pull harness inboard at base of center pillar for accessibility. Power windows a r e operated by a rectangular shaped 1 2 volt series-wound motor with an internal circuit breaker and a self-locking rubber coupled gear drive. The harness to the door window motor connector is designed with a locking embossment to insure a positive connection. When disengaging the harness connector from the door motor, it is necessary to depress the thumb release. When installing the harness, the thumb release must be held depressed until the embossment on the female connector is locked in the hole of the motor connector. Fig. 11-1 1-Rear Quarter Window Wiring Less 67 Styles - "A" Coupe Some r e a r quarter window motors and ventilator motors a r e designed with a locking type connector which should not be disengaged. When testing o r removing the motor, the in-line connector located inboard of the inner panel should be disengaged. I Fig. 11-12-Left 1. Flat to Round Wire 2.

Refer to electrical introduction for specific locations. Relay CONNECTOR Oldsmobile and Cadillac styles only - In addition to the circuit breaker, a relay is used in the circuit. The relay prevents the operation of the power windows until the ignition switch is turned '(on". Cut-Out Switch A cut-out switch (Cadillac styles only) installed on the left front door a r m rest, is designed to temporarily by-pass the relay circuit s o the windows may be operated only from the master control switch when the ignition is in the off position.

When the cut-out button is released, the button will return to the "NORMAL" position. The cut-out switch button should be set in the "LOCK" position when ignition switch is "ON') to permit normal operation of power windows from all switch locations. If the control button is left in the "NORMAL" position with the ignition switch on, the windows will operate only from the master control switch. Power Window Circuit Checking Procedures Failures in a circuit a r e usually caused by short circuits o r open circuits. Open circuits a r e usually caused by breaks in the wiring, faulty connection o r mechanical failure in a component such a s a switch o r circuit breaker. Short circuits a r e usually caused by wires from different components of the circuit contacting one another o r by a wire o r component grounding to the metal of the body due to a screw through the wire, insulation cut through by sharp metal edge, etc. Fig. Il-16-Left Rear Door Power Window Wiring "Au-39 Styles - ELECTRICAL Fig. 11-17-Right 11-9 Side Power Window Wiring " A " 35-55-65 and 69 Styles It may be necessary to use only one o r all of the procedures outlined to locate an electrical failure in the circuit. If the location of the failure is evident follow only the steps required to check the affected wire o r component. If the location of the failure is not evident, follow the procedure a s outlined. Be s u r e to check the harness connectors for proper engagement and become familiar with the typical circuit diagrams. (See Figs. 11- 23 through ,2f- 30).
