Steps
Remove the door panel
Switch off the ignition. Release the latch and door-pull trim, unplug the switch panel, and remove the three exposed 10 mm bolts. Free the panel clips and disconnect the latch rods, speaker, and courtesy-light wiring before lifting the panel away.
Support the glass and remove the regulator
Disconnect the window motor and release its wiring clips. Remove the inner stamped panel fasteners and the regulator and motor bolts. Support the glass while loosening its track bolts, raise it by hand, and tape it securely at the top before removing the regulator assembly.
Transfer the motor and install the regulator
Separate the motor from the old regulator and transfer it to the replacement if the motor is serviceable. Secure the motor, route the wiring through the inner panel, and reinstall the regulator assembly and panel fasteners in the door.
Reconnect the glass and test travel
Reconnect the window switch temporarily and position the regulator clips at the glass access points. Support the glass while removing the tape and lowering it onto the clips, then secure the glass bolts. Cycle the window up and down and confirm smooth operation.
Reinstall the door panel
Switch off the ignition, reconnect the speaker, courtesy light, latch rods, and wiring harnesses, then clip the inner panel components back in place. Reinstall the outer panel, switch panel, door-pull trim, and fasteners, then test all door controls.
