Window Regulator, Front Driver Side

The first step in front side door Window Regulator replacement involves removing the door trim panel followed by detaching the water deflector. Proceed by taking out the energy absorber retainers and the energy absorber from the door before removing the covers showing the regulator bolt positions. You should remove the window guide attachment to regulator bolts before lifting the window to its maximum vertical position. First disconnect the power connector from the regulator motor followed by loosening and then removing the upper bolt retaining the regulator to the upper door. Finally remove the motor retaining nut and detach the regulator. Unscrew the lower door bolts which retain the regulator and turn the upper part forward before lifting the regulator out of the opening. Transfer the Window Regulator motor to the regulator before partially attaching the upper bolt to let you insert the regulator through the door opening standing at a semi-horizontal angle. Lower the regulator into place on the door sheet metal by rotating it vertically after its full insertion into the door cavity using the pre-installed upper bolt. Lower the window to sit at the window guide of the regulator and then tighten the regulator window carrier bolts gently. First adjust the window to be in run channels then apply the nut onto the door component to attach the motor while torqueing it at 9 nm (80 lb in). Then secure the upper and lower bolts securing the regulator to the door before tightening them to 10 nm (88 lb in). Install the device connectors to regulator motors while adding energy absorber retainers and absorbers and fastening water deflectors before applying the door trim panel.

Loosely tighten the regulator window carrier bolts.

Lower and hang the regulator onto the door sheet metal using the previously installed upper bolt, then remove the window support and lower the window to the window guide on the regulator.

Remove the water deflector.
