  Q: How to service and replace a window regulator on a Cadillac XLR?

  A:

  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.
