POWER WINDOW MOTOR
NOTE: On Dakota, window motor and regulator are serviced as an
assembly.
1) Remove door trim panel. See DOOR TRIM PANEL 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 under REMOVAL & INSTALLATION. If motor grunts
and does not move, 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.
POWER WINDOW SWITCH
1) Remove window switch from door trim panel. See POWER
WINDOW SWITCH under REMOVAL & INSTALLATION. Using an ohmmeter, check
switch continuity. See appropriate WINDOW SWITCH CONTINUITY table.
Replace power window switch as necessary. See appropriate
illustration. See Figs. 1 - 6.
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.

SYSTEM TESTS
ALL WINDOWS INOPERATIVE
Caravan, Town & Country, & Voyager
1) Check Positive Temperature Coefficient (PTC) for power
window system. See TROUBLE SHOOTING. Replace PTC as necessary. If PTC
is okay, go to next step.
2) Remove driver's power window switch. See POWER WINDOW
SWITCH under REMOVAL & INSTALLATION. Turn ignition on. Using test
light, connect ground lead to harness connector terminal No. 13 (Black

Ram Van & Ram Wagon
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 does not move freely, check window glass,
tracks and regulator for sticking or binding. Repair as necessary and
recheck system operation. If glass moves freely, go to next step.
2) Disconnect negative battery cable. Disconnect and remove
power window switch in door with inoperative window. See POWER WINDOW
SWITCH under REMOVAL & INSTALLATION. Connect negative battery cable.
Turn ignition on. Measure voltage between passenger power window
switch wiring harness connector terminal (Tan wire) or driver power
window switch wiring harness connector terminal (Tan wire) and ground.\
See WIRING DIAGRAMS. If battery voltage is not present, repair open
Tan wire as necessary. If battery voltage exists, and inoperative
window is on driver side, go to step 4). If battery voltage exists,
and inoperative window is on passenger side, go to next step.
NOTE: Passenger's power window switch is grounded through driver's
power window switch.
3) Disconnect negative battery cable. Check continuity
between ground and passenger's power window switch harness connector
terminals No. 2 (Brown/White wire) and No. 4 (Violet/White wire). Se\
e
WIRING DIAGRAMS. If continuity exists on both circuits, go to step 5).
If continuity does not exist on either or both circuits, repair open
circuit.
4) Check power window switch. See POWER WINDOW SWITCH under
COMPONENT TESTS. Replace faulty power window switch as necessary. If
switch is okay, go to next step.
5) Using an ohmmeter, check continuity of each circuit
between inoperative power window switch wiring harness connector and
corresponding power window motor wiring harness connector terminal.
See WIRING DIAGRAMS. If continuity does not exist in one or more
circuits, repair open circuit(s) as necessary. Recheck system
operation. If continuity exists in all circuits, power window switch
and switch circuits are okay. Check power window motor. See POWER
WINDOW MOTOR under COMPONENT TESTS.
REMOVAL & INSTALLATION

systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
