Window Regulator, Front Driver Side

Begin by lowering the front door window before disconnecting the battery as the first step to replace the front door Window Regulator. Begin by lowering the door window and disconnecting battery power. After that, remove the door trim panel and disconnect the door panel electrical connector. The large water deflector requires removal to access the back of the door before you remove small mastic seals near the top and a small plug at the bottom. This will provide access to both upper regulator mounting fasteners. Excise the water deflector before you detach the electrical harness by taking off both radio speaker fasteners and electrical lock. First disconnect the regulator motor electrical connector by unlocking its connector lock then sliding it upward. Create a mark for regulator location that indicates both regulator pad mounts and their proper depth for assembly. Use the inner door access opening to remove the regulator after disconnecting its lower channel studs and motor studs as well as upper channel studs while compacting the regulator. To replace the Window Regulator use the original jack screw adjustments on the new unit before compacting the assembly until ready for installation by inserting the complete component with motor first into the door. Guide the motor studs through the inner panel of the door. Insert the motor nuts covering them to a torque of 10 n.m (89 lb in). Afterward, position the regulator channel studs through the door holes before installing the loose nuts. Thread the electrical connector to the motor before securing the connector lock into position on the seated spot. Adjust the installed window until it sits correctly with the door opening. Use the battery power to secure the door window switch after guiding the Window Regulator clamps to reach the glass which must be tightened to 16 n.m (12 lb ft). Begin by securing nuts on the regulator channel studs as follows: upper forward and upper rearward and then lower forward and lower rearward turning each stud to 10 n.m (89 lb in). The small mastic seals must be placed in the window clamp sight access holes while connecting the harness electrical connector to the speakers before installing the connector lock. The speaker assembly receives its uppermost screws for mounting onto the door which also enables correct positioning of the speaker tab before installing the remaining screws at a torque of 3 n.m (27 lb in). First reinstall the water deflector and then complete the electrical connector connection of the door panel before putting back the door trim panel. Drill holes according to the specification to check window drainage before fitting and installing the access plug into the lower door section to inspect electric functions of all window(s), mirror(s) and door switch operation.

The first step for applying new front door Window Regulator installation is to lower the door window and disable the car battery. A large water deflector must be taken out first after removing both the door trim panel and door panel electrical connector to reveal the door back section. Access the upper and lower regulator mounting fasteners by removing small mastic seals from the door's top section and small plug from the bottom. To proceed disconnect the electrical harness from the radio speaker first by removing fasteners from the speaker then its electrical connector lock before removing the radio speaker from the door while avoiding contact with the water deflector. Begin by removing the door window and disconnecting the regulator motor electrical connector through the process of sliding the connector lock. Identify where to position the regulator so it can be put back together later, take note of where the regulator pads mount on the door. The nuts from all three regulator components must be removed. After compacting the regulator you can pull it out through the inner door access opening. To install a new Window Regulator begin by adjusting the replacement assembly jack screws to match the original regulator settings while compacting the regulator assembly before completely inserting the unit with motor forward into the door. Feed the motor studs through the door inner panel before screwing nuts onto them while torquing them to 10nm (89lb in). Insert the regulator channel studs through door holes before installing the nuts on them slightly tight. Connect the electrical connector to the motor before securing the lock of the connector to its seated position. Adjust the window placement carefully for the door opening before connecting the battery power source. Connect the door window switch before running the Window Regulator clamps to meet the glass while tightening them to 16 n.m (12 lb ft). First tighten the regulator channel studs nuts starting with the upper forward then follow with the upper rearward and finish with the lower forward and lower rearward applications of 10 n.m force (89 lb in torque). After placing the tiny mastic seals into the window clamp sight access holes you should connect the harness electrical connector to the speakers then lock the connector. Install the speaker assembly to the door by using first the uppermost screws then check the speaker tab alignment before completely tightening the screws to 3 n.m (27 lb in). Put back the water deflector after plugging in the door panel electrical connector then install the door trim panel. Check if the windows fit properly followed by speaker trim installation then connect the door access plug and test if all electrical components of the window(s) mirror(s) and door switch work correctly.

Upper forward, upper rearward, lower forward, lower rearward, each to 10 N.m (89 lb in).

Guide them into the door holes and loosely install the nuts.

Inspect the window fit and adjust as necessary.
