Power Windows Dodge Cab & Chassis R2500

DESCRIPTION & OPERATION

A permanent magnet motor moves each of the power windows, including power vent windows. A positive and negative battery connection to either of the 2 motor terminals will cause the motor to rotate in one direction. Reversing current through these same 2 connections will cause the motor to rotate in the opposite direction. Each individual motor is grounded through the master switch by a wire attached to the instrument panel reinforcement.

Remove door trim panel. See DOOR TRIM PANEL under REMOVAL & INSTALLATION. Loosen bolts holding window to regulator. Raise window fully, seating window in frame. Tighten bolts. Install door trim panel.

TROUBLE SHOOTING

1. Inspect fuse No. 2 (40-amp) located in Power Distribution Center (PDC). PDC is located in left side of engine compartment.
2. Inspect circuit breaker No. 1 (20-amp) in fuse block. Fuse block is located under left side of instrument panel.
3. Inspect power window system ground circuit. See «WIRING DIAGRAMS»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) .

CIRCUIT BREAKER

1. Locate circuit breaker for power window system. See «TROUBLE SHOOTING»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows__trouble-shooting) . Pull circuit breaker out slightly, but ensure circuit breaker terminals still contact terminals in fuse block.
2. Connect voltmeter negative lead to ground. Using voltmeter positive lead, check both terminals of circuit breaker for battery voltage. If voltmeter indicates battery voltage at both terminals, circuit breaker is okay.
3. If voltmeter indicates battery voltage at one terminal only, replace faulty circuit breaker. If voltmeter indicates no voltage at either terminal, check for an open or shorted circuit to circuit breaker. Repair as necessary and recheck system operation.

POWER WINDOW MOTOR TEST

1. Remove door trim panel. See «DOOR TRIM PANEL»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Disconnect window motor connector. Using jumper wires, apply battery voltage to window motor terminals. Motor should operate, unless window is already at maximum travel.
2. Reverse jumper wires. Window should move in opposite direction. If window does not move in either direction, replace window motor.
3. If motor operates in one direction only, replace motor. See «POWER WINDOW MOTOR R & I»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) . Disconnect window glass from regulator plate. Check window glass, tracks and regulator for sticking, binding or improper adjustment. Repair as necessary and recheck system operation.

Scheme 1

1. Remove window switch from door trim panel. See «POWER WINDOW SWITCH»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Using an ohmmeter, check switch continuity. See appropriate table: «DRIVER'S WINDOW SWITCH CONTINUITY»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows). «PASSENGER'S WINDOW SWITCH CONTINUITY»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows).
2. Vehicles equipped with Auto Down feature have electronic components in switch to actuate Auto Down. To test, check switch continuity, reconnect switch, turn ignition on and test feature. If Auto Down does not work, replace switch. Replace power window switch as necessary. (Scheme 1)

ALL WINDOWS INOPERATIVE

1. Check circuit breaker for power window system. See «TROUBLE SHOOTING»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows__trouble-shooting) . Replace circuit breaker as necessary. If circuit breaker is okay, go to next step.
2. Remove left front power window switch. See «POWER WINDOW SWITCH»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) under REMOVAL & INSTALLATION. Check for continuity between ground and terminal No. 3 at driver power window switch wiring harness connector. See «WIRING DIAGRAMS»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) . If continuity exists, go to next step. If continuity does not exist, repair open in Black/Orange wire between driver power window switch connector and ground.
3. Turn ignition on. Measure voltage between ground and terminal No. 4 at driver power window switch wiring harness connector. If battery voltage is present, check driver power window switch. See «POWER WINDOW SWITCH»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) under COMPONENT TESTS. If battery voltage is not present, repair open Tan wire between driver power window switch connector and ignition switch. See «WIRING DIAGRAMS»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) .

ONE WINDOW INOPERATIVE

Note. Window glass must be free to slide up and down for power window motor to function properly. If glass is not free to move up and down, motor will overload and trip the circuit breaker.

1. Place window glass halfway between up and down positions. Verify glass can be moved slightly from side to side, front to rear, and up and down. If glass is not free to move, check window glass, tracks and regulator for sticking, binding or improper adjustment. Repair as necessary and recheck system operation. If glass moves freely, go to next step.
2. Check power window switch. See «POWER WINDOW SWITCH»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) under COMPONENT TESTS. Replace faulty power window switch as necessary. If switch is okay and driver's door window is inoperative, see «POWER WINDOW MOTOR TEST»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows__power-window-motor-test) . If switch is okay and any door window is inoperative besides driver's window, go to next step.
3. Ensure power window switch is disconnected. Turn ignition on. Measure voltage between ground and terminal No. 3 (Tan wire) at passenger power window switch wiring harness connector. See «WIRING DIAGRAMS»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) . If battery voltage is present, go to next step. If battery voltage is not present, repair open Tan wire as necessary.
4. Using an ohmmeter, check continuity of each circuit between inoperative power window switch wiring harness connector and corresponding driver's power window switch wiring harness connector. See «WIRING DIAGRAMS»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows) .
5. If continuity exists in all circuits, power window switch and switch circuits are okay. Check power window motor. See «POWER WINDOW MOTOR TEST»(/dodge/cab-chassis-r2500/1996-2002/remont/windows/#power-windows__power-window-motor-test) . If continuity does not exist in one or more circuits, repair open circuit(s) as necessary. Recheck system operation.
