DOOR WINDOWS
Window regulators are individually powered by a 12-volt reversible motor located in each door. The motor contains an internal circuit breaker requiring 1 to 3 minutes to reset.
The motor, bolted to regulator assembly, utilizes a self-locking gear drive. A 2-way control switch is located on each door, with a master control switch located on left door. The window cannot be operated from door control switches unless ignition is turned on.
CIRCUIT BREAKER
A 30-amp circuit breaker is mounted on fuse block.
CONTROL SWITCHES
In addition to individual control switches adjacent to individual windows, a master control switch is mounted on left door trim pad.
ACCESSORY JUNCTION BLOCK
Junction block is located on reinforcement at left shroud. It supplies current to power operated circuits. Current is supplied to junction block from circuit breaker. Power window harness plugs into junction block.
WINDOWS WILL NOT OPERATE WITH IGNITION ON
Open circuit or short in power feed circuit. Switch defective.
RIGHT WINDOW OPERATES WITH MASTER SWITCH BUT WILL NOT OPERATE WITH RIGHT CONTROL SWITCH, LEFT WINDOW OPERATES
Open circuit or short in front harness power feed circuit.
Check power feed to circuit breaker. If no power is available, feed wire is open or shorted. Test breaker output terminal. If power fails, breaker is inoperative.
MASTER CONTROL SWITCH
Check power feed Pink wire at switch. If power fails, test wire between relay and master switch.
WINDOW CONTROL SWITCH
- Connect one lead of test lamp to switch connector feed wire and ground other lamp lead. If lamp does not light, an open short circuit exists between switch and power source.
- Insert one end of a jumper wire in switch connector and other end of jumper to motor lead in connector. Repeat procedure for motor lead terminal. If motor operates with jumper wire but does not operate with switch, replace switch.
WINDOW SWITCH TO WINDOW HARNESS
Disconnect harness connector from motor. Insert one end of a jumper wire in switch connector and other end of jumper to motor lead in connector. Using a test lamp, check for current at motor connector. If lamp does not light, switch to motor harness is shorted or has open circuit. Check other terminal using same procedure.
WINDOW MOTOR
Check power feed to motor terminals. If power is available, check motor ground. Inspect window regulator and channels for possible binding. Connect a jumper wire to other motor terminal. Motor should operate window up and down. If not, replace motor.

WINDOW REGULATOR & MOTOR
| CAUTION | Disconnect electrical connections before removing regulator assembly from window. |
- Raise window to full "UP" position and tape glass to door frame to prevent it from falling. Disconnect battery negative cable and remove door trim panel. On "S" series, remove door trim panel, armrest bracket and inner panel water deflector.
- On "C" and "K" series, remove remote control bolts and place control assembly aside, if necessary. On all models, remove window regulator-to-door panel attaching screws.
- On "C", "K" and "M" series, disconnect harness from window regulator. On "C" and "K" series, slide window regulator assembly rearward, disengaging rollers from sash panel. On "M" series, remove rivets attaching window regulator to inner panel. On "C", "K" and "M" series, remove window regulator assembly.
- On "S" series, disconnect harness from motor. Disengage roller or window regulator lift arm from glass run channel. Remove window regulator through access hole. WARNING: Window regulator lift arm is under tension from counterbalance spring. Sector gear must be locked to avoid personal injury.
- On "C" and "K" series, drill a hole through sector gear and back plate. Do not drill closer than 1/2" (13 mm) to edge of sector gear or back plate. On "C", "K" and "M" series, install sheet metal screw (No. 10 - 12 x 3/4") into hole to lock sector gear. Remove motor-to-regulator attaching screws (rivets on "M" series) and remove window regulator from motor.
- On "S" series, drill a hole through window regulator sector gear and back plate and install a bolt and nut to lock sector gear. Using a 3/16" drill bit, drill out motor attaching rivets and remove motor.
Installation
- On "C", "K" and "M" series, lubricate motor drive gear and regulator sector teeth with a lubricant that is effective down to -20°F (-29°C). Make sure that motor pinion gear teeth mesh properly with sector gear. Remove screw locking sector gear. To complete installation, reverse removal procedure.
- On "S" series, install motor on regulator using Riveter (J-29022) and install 3/16" rivets or install 3/16" nuts and bolts. Remove nut and bolt used to secure sector gear. To complete installation, reverse removal procedure.
