• Q: How to replace the front door window regulator on 2008 Cadillac XLR?

  A: The first step to replace the front door Window Regulator requires lowering the door windows with battery disconnection. Start by taking off the door trim panel before detaching the door panel electrical connector. Acces to the door's rear section is achieved by removing the large water deflector so you can take out small mastic seals near the top and a small plug at the bottom to access regulator mounting fasteners. First disconnect the radio speaker electrical harness then remove its fasteners to access it. Remove the door window followed by disconnecting the regulator motor electrical connector then raising the connector lock to separate the harness. Record the regulator position for future assembly and unfasten the nuts securing the lower channel studs with the motor studs along with the upper channel studs. Insert the compressor into the inner door access opening while it is compacted. Installation of a new regulator requires adjusting its replacement assembly jack screws until they reflect original specifications followed by compacting the assembly for insertion into the door with the motor at the front. Insert the door inner panel motor studs through their openings before installing nuts and tightening them to 10 n.m (89 lb in). Use the door holes to guide the regulator channel studs and apply loose nuts to them. Insert the electrical connector into the motor before seating the connector lock at its position. Set the window panel correctly before installing it against the door opening. Belting the battery power followed by connecting the door window switch allows you to feed the Window Regulator clamps towards the glass while tightening them to 16 n.m (12 lb ft). Heat and tighten the regulator channel studs in the sequence of upper forward, upper rearward and lower forward, lower rearward to 10 n.m (89 lb in) torque. Secure the small mastic seals through window clamp sight access holes after plugging the speaker harness electrical connector to the hardware and engaging the locking mechanism. Mount the speaker assembly to the door with the uppermost screws first which allows verification of speaker tab placement then proceed with installing the rest of the screws until they reach 3nm (27 lb in) torque. After installing the water deflector users should attach the door panel electrical connector and mount the door trim panel. Position the access plug inside the door opening at the bottom section followed by a fit and adjustment check of the window before proceeding with the installation process. End the process by checking the electrical operation of windows and mirror functionality and door switches before performing a windows reinitialization.
