Power Windows Chevrolet Cutaway P30

DESCRIPTION

POWER WINDOW SYSTEM

A Permanent Magnet (PM) motor operates each of the power windows. Each motor raises or lowers the glass when the voltage is supplied to it. The direction the motor turns depends on the polarity of the supply voltage. The switches control the supply voltage polarity. The master door lock/power window switch assembly controls both of the motors. The Right window switch controls only the Right window motor. Each motor is protected by a built-in circuit breaker. If a window switch is held too long with the window obstructed or after the window is fully up or down, the circuit breaker opens the circuit. The circuit breaker resets automatically as it cools.

POWER WINDOW HARNESS

This harness starts at the fuse block and routes to the left and right along the instrument panel. The harness then routes into the left and right front doors. At the left door hinge pillar, the harness routes up to the left roof halo panel, back to the first roof frame, branches to the right side of the van and rearward to the rear door. The branch that went to the right side routes down the side door hinge pillar and into the side door.

LEFT WINDOW SWITCH

When the ignition switch is in run, battery voltage is supplied to the master door lock/power window switch assembly, the power window circuit breaker, and the Pink (76) wires. See WIRING DIAGRAMS . When any of the up switches are operated, battery voltage is supplied to the window motor through the Dark Blue (164) wire. The window motor is grounded through the DN contact. The motor runs to drive the window up. When any of the DN switches are operated, battery voltage is supplied to the window motor in the opposite direction through the Brown (165) wire. The window motor is grounded through the up contact. The motor runs to drive the window down.

RIGHT WINDOW SWITCH

When the ignition switch is in run, battery voltage is supplied to the Right window switch through the power window circuit breaker and the pink (76) wires to terminal "A". See WIRING DIAGRAMS . When the up switch in the Right window switch is operated, battery voltage is supplied to the Right window motor through the Dark Blue (666) wire. The motor is grounded through the Brown (667) wire, the DN contact in the Right window switch, the Tan (167) wire and the DN contact in the master door lock/power window switch assembly.

The motor runs to drive the window up. When the DN switch is supplied in the Right window switch is operated, battery voltage is supplied to the Right window motor in the opposite direction through the Brown (667) wire. See WIRING DIAGRAMS . The motor is grounded through the Dark Blue (666) wire, the up contact in the Right window switch, the Dark Blue/White (166) wire and the up contact in the master door lock/power window switch assembly. The motor runs to drive the window down.

PRELIMINARY INSPECTION

Verify customer complaint by operating suspected system. Visually inspect for damage to the power window circuit breaker, it damaged replace. Inspect for blown fuses and faulty circuit breaker. (Scheme 2) Inspect for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found, diagnose by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
