GENERAL INFORMATION

Front and rear door window lift motors are of the permanent magnet type. A positive and negative battery connection to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these same two connections will cause the motor to rotate in the opposite direction.

Each individual motor is grounded through the master switch by a black wire attached to the left cowl panel.

It is necessary that the window be free to slide up and down in the glass channels or tubes and tracks. If the window is not free to move up and down, the window lift motor will not be able to move the glass.

To determine if the glass is free is to disconnect the regulator from the glass lift plate, and slide the window up and down by hand. For conventional armsector regulators, after the lift plate is detached from the glass, it will slide off the regulator drive arm. Flex-drive regulators may be detached the same way or by removing one screw holding the flex rack to the lift plate drive arm.

WIRING VOLTAGE TEST

The following wiring test determines whether or not voltage is continuous through the body harness to switch.

(1) After removing switch for testing purposes, carefully separate multiple terminal block on wiring harness from switch body. With ignition switch ON connect one lead of test light to black (or gray) wire terminal and touch other test light lead to tan wire terminal. If the test light comes on, the wiring circuit between the battery and switch is functional. If light does not come on, check 30 amp main fuse (circuit breaker) or for a broken wire. For wiring, specific connector type and location, refer to Group 8W, Wiring Diagrams.

WINDOW LIFT SWITCH TEST

For switch testing, remove the switch from its mounting. Using an ohmmeter, refer to Window Switch Continuity Charts to determine if continuity is correct. If the results are not obtained, replace the switch.

AC and AY Bodies are equipped with an Auto-Down feature. This feature allows the operator to lower the driver's window without having to hold the switch in the down position. The Auto-Down feature can be activated by pressing the down switch past the first detent (Stop).

To test the auto-down feature, operate the window in the normal up and down mode. If the window works correctly in the normal mode, but not in the auto-down mode, replace the switch.

To test the window switch (other than Auto-Down mode), install a known good switch.

WINDOW LIFT MOTOR TEST

(1)Connect positive (+) lead from a test battery to either of the two motor terminals.

(2)Connect negative (-) lead from test battery to remaining motor terminal.

(3)The motor should now rotate in one direction to either move window up or down.

(a)If window happens to already be in full UP position and motor is connected so as to rotate in UP direction no movement will be observed.

(b)Likewise, motor connected to DOWN direction rotation, no movement will be observed if window is already in full DOWN position.

(4)Reverse battery leads (steps 1 and 2 above) and window should now move. If window does not move, remove motor. See below for motor removal from vehicle.

Fig. 1 Motor Lubrication

When gear and pinion assembly is replaced in gear box, lubrication of gear box, gear pinion and seal is necessary.

In the event there is no lubricant in gear box, fill with MOPAR multi-mileage lubricant or equivalent. Apply a liberal amount of lubricant to inside area of seal marked A as illustrated in Fig. 1 and sealing surface at center area of gear and pinion coupling. Also lubricate center gear box shaft and worm gear.

MOTOR REPLACEMENT CONVENTIONAL REGULATORS

The following procedure describes replacement of a defective motor without removing window regulator or detaching any window system components. This method of motor replacement is not acceptable if any of window system parts are loosened or removed from door such as:

²Lift channels

²Up stops

²Tracks and pivot brackets

²Are already loose by deficiency

²Are to be loosened or removed from the door.

Then use method of repair where entire regulator is removed from door (Fig. 2 through 9).

REMOVAL

(1) Raise window to full UP position and keep it there at all times while replacing motor. If window is in any position other than full UP and motor is separated from spring loaded regulator, then regulator counterbalance spring will tend to propel window upwards.

WARNING: PLACE A WINDOW BLOCK IN DOOR THAT WILL POSITIVELY PREVENT WINDOW FROM GOING DOWN. THIS ACTION WILL PREVENT INJURY THAT COULD BE CAUSED BY INCORRECT INSTALLATION OF COUNTERBALANCE SPRING OR UPWARD MOVEMENT OF THE WINDOW.

(2)Disconnect wiring connector from motor which is located about eleven inches from motor.

(3)Remove three mounting screws that hold motor gearbox to regulator. Remove third screw that secures motor tie-down bracket to inner panel if so equipped.

Fig. 7 Power Window Converitble Ð AJ Body

There are three holes in inner panel which provide access to three mounting screws that secure gearbox to regulator (Fig. 2).

For AJ body vehicles, it will be necessary to reach through opening in inner door panel and around behind regulator to gain access to motor gearbox retaining screws.

(4) To remove motor from regulator, grip motor housing and pull motor towards inner or outer panel, depending on regulator type. Some rocking or twisting action may be necessary to disengage motor from regulator.

WARNING: DO NOT HAVE ANY HANDS OR FINGERS IN SECTOR GEAR AREA WHERE THEY CAN BE PINCHED BY SMALL MOVEMENTS OF REGULATOR LINKAGE.

INSTALLATION

New motor gearbox retaining screw holes are not threaded. It may be desirable to tap holes before attempting assembly.

(1)Install new motor on regulator by positioning motor gearbox so that it engages regulator sector teeth.

(2)Position motor so that center post gearbox fits into its pilot hole in plate. A slight rotational or rocking movement may be necessary to bring three motor gearbox screw holes into proper position.

(3)Install three gearbox screws and one tie down bracket screw, if applicable. Tighten to 5 to 7 Nzm (50 to 60 in. lbs.) torque.

(4)Connect pigtail wiring harness connector.

(5)Remove window block.

(6)Actuate regulator with switch to verify satisfactory operation.

BENCH REPAIR OF REGULATOR AND MOTOR CONVENTIONAL REGULATORS

To repair or inspect the entire electric window regulator, remove from the door as follows:

REMOVAL

(1)Disconnect wiring connector from motor.

(2)Hold glass in the up position.

(3)Remove rivets and/or screws that hold regulator and motor to inner door panel.

(4)Maneuver regulator assembly by hand to disengage the drive arm slider from the glass lift channel. Remove from door.

REPAIR

If entire regulator is not being replaced, repair as follows:

WARNING: REMOVE COUNTER BALANCE SPRING BEFORE THE MOTOR IS REMOVED. IF IT IS NOT, THE SPRING TENSION WILL CAUSE THE REGULATOR ARMS TO CLOSE AS SOON AS THE MOTOR IS REMOVED AND COULD SERIOUSLY INJURE YOUR FINGERS.

(1)Remove regulator as described above.

(2)Secure regulator in vise to prevent sector gear from rotating.

(3)Remove counter balance spring.

(4)Remove three motor attaching screws and remove motor.

(5)Inspect regulator for:

(a)Sector gear teeth must not be broken or severely worn.

(b)All rivets and sliders must be securely attached.

(c)Parts must not be bent or cracked.

(d)Sector gear must rotate freely.

(e)Perform window lift motor test as described above.

INSTALLATION

(1)Install motor and attach with three motor attaching screws. If installation of new motor is necessary, it may be desirable to tap motor retaining screw holes.

(2)Install counter balance spring.

(3)Replace regulator in door by reversing Removal steps 1, 2 and 3.

(4)Regulators may be secured to door panel using rivets or 1/4-20 X 1/2 screws and nuts.
