Power Windows Chevrolet Beretta I

DESCRIPTION & OPERATION

CIRCUIT OPERATION

A permanent magnet (PM) motor operates each of the power windows. Each motor raises or lowers the glass when voltage is supplied to it. The direction the motor turns depends on the polarity of the supply voltage. The switches control the supply voltage's polarity.

The master switch assembly controls all of the motors. Each power window switch controls only one of the motors.

Each motor is protected by a built in electronic circuit breaker Positive Temperature Coefficient (PTC). If a power window switch is held too long with the window obstructed or after the window is fully up or down, the PTC resistance increases. The resistance returns to normal after voltage is removed from the motor.

MASTER SWITCH OPERATION

When the ignition switch is in RUN position, battery voltage is applied to the master switch assembly through circuit breaker No. 12 and PNK wire. See WIRING DIAGRAMS . When any of the UP switches in the master switch assembly are operated, battery voltage is applied to the power window motor through the DK BLU or DK BLU/WHT wires.

The power window motor is grounded through the DN contact in the master switch assembly. The motor runs to drive the window up. When any of the DN switches in the master switch assembly are operated, battery voltage is applied to the power window motor in the opposite direction through the BRN or TAN wires. The power window motor is grounded through the UP contact in the master switch assembly. The motor runs to drive the window down.

If the left front DN switch in the master switch assembly is pressed past the first detent, the window will travel to the full down position without holding the DN switch depressed.

POWER WINDOW SWITCH OPERATION (4-DOOR ONLY)

When the ignition switch is RUN, battery voltage is applied to the power window switches through circuit breaker 12 and the PNK wires to terminal A. See WIRING DIAGRAMS . When the UPswitch in the left rear power window switch is operated, battery voltage is applied to the left rear power window motor through the DK BLU wire.

The motor is grounded through the BRN wire, and the DN contact in the master switch assembly. The motor runs to drive the window up. When the DN switch in the left rear power switch is operated, battery voltage is applied to the left rear power window motor in the opposite direction through the BRN wire. The motor is grounded through the DK BLU wire, and the UP contact in the master switch assembly. The motor runs to drive the window down. The other windows operate similarly from their individual power window switches.

LUBRICATION

All door hardware mechanisms can be lubricated with part no. 1052349, Lubricate Spray Lube "A", part no. 1052196, Lubricate Auto-Lube "A", or equivalent.

FRONT DOOR LOCK HANDLE (BERETTA)

PRELIMINARY INSPECTION

Verify customer complaint by operating suspected system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. 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, perform system operation check. See SYSTEM OPERATION CHECK .

1. If all the power windows do not operate, check the circuit breaker 12in instrument panel fuse block.
2. Check that ground G300 is clean and tight.
3. If a motor's internal circuit breaker trips, it will not reset until voltage is removed from the motor.

SYSTEM OPERATION CHECK

1. Use the System Check Table as a guide to normal operation. (Scheme 7)
2. If problem exists, repair by symptom. See «SYMPTOM INDEX»(/chevrolet/beretta/i-1987-1996/remont/windows/#power-windows).
