light DODGE RAM 1999 Service Repair Manual

window motor to function properly. If glass is not free to
move up and down, motor will overload and trip the circuit
breaker.
Dakota & Ram Pickup
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, binding or improper adjustment.
Repair as necessary and recheck system operation. If glass moves
freely, go to next step.
2) Disconnect negative battery cable. Remove power window
switch from door with inoperative window. Disconnect power window
switch connector. Connect negative battery cable. Turn ignition on.
Check for battery voltage at power window switch harness connector
terminal No. 5 (driver's window) or terminal No. 11 (passenger's
window). If battery voltage does not exist, repair open Tan wire
between junction block and power window switch. If battery voltage
exists, go to next step (inoperative passenger's window) or go step 4)\
(inoperative driver's window).
3) Disconnect negative battery cable. Check for continuity
between ground and passenger window switch harness connector terminals
No. 1 (Brown/White wire) and 2 (Violet/White wire). If continuity
exists, go to next step. If continuity does not exist, repair open
circuit in wiring harness between window switches.
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) Check for continuity between window switch wiring
connector terminals and corresponding window motor wire connector
terminals of inoperative power window. 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. If
continuity does not exist in one or more circuits, repair open
circuit(s) as necessary. Recheck system operation.
Durango
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, binding or improper adjustment.
Repair as necessary and recheck system operation. If glass moves
freely, and is not driver's window, go to next step. If driver's
window is inoperative, check power window motor. See POWER WINDOW
MOTOR under COMPONENT TESTS. If Auto Down feature is the only problem,
replace driver's switch. If switch LED is the only problem, replace
unlit switch.
2) Disconnect negative battery cable. Remove power window
switch from door with inoperative window. See POWER WINDOW SWITCH
under REMOVAL & INSTALLATION. Connect negative battery cable. Turn
ignition on. Check for battery voltage at power window switch harness
connector Yellow wire. If battery voltage does not exist, repair open
circuit to master window switch. If battery voltage exists, go to next
step.
3) Test power window switch continuity. See POWER WINDOW
SWITCH under COMPONENT TESTS. Replace faulty switch as necessary. If
switch is okay, go to next step.
4) Check for continuity in each circuit between master window
switch and switch for inoperative window. See WIRING DIAGRAMS. If
continuity does not exist in any circuit, repair open circuit as
necessary. If continuity exists in all circuits, test power window
motor. See POWER WINDOW MOTOR under COMPONENT TESTS.

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
CAUTION: When battery is disconnected, vehicle computer and memory
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
before disconnecting battery.
DOOR TRIM PANEL
Removal & Installation (Caravan, Town & Country, & Voyager)
1) Using a trim stick, pry courtesy light from door trim.
Disconnect courtesy light connector. Remove door assist handle (if
equipped). Remove door pull cup (if equipped). Remove screws attachin\
g
trim panel to door below map pocket (if equipped). Using a trim stick,\
remove screw cover from switch panel.
2) Remove screws securing switch panel to door trim and
remove panel. Using a trim stick, remove seat/mirror memory switch (if
equipped). Remove screw securing door trim to door panel from behind
inside latch release handle.
3) Disengage clips holding door trim to door frame around
perimeter of panel. Tilt top of trim panel away from door to gain
access to latch linkage. Disengage clip holding linkage rod to inside
latch release handle. Separate linkage rod from latch handle. Remove

3) Install cable guide and drum into new window motor. To
install drum onto window motor shaft, a slight rotation of drum may be
necessary.
4) Using needle nose pliers, rotate drum. If drum still does
not align with motor shaft, with aid of an assistant, lower window
glass 1-2 inches. Drum will rotate when glass is lowered.
5) Install cover plate onto window motor. Connect window
motor connector. Remove tape holding window in place. Test window
operation. To complete installation, reverse removal procedure.
