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.
