How to Replace Power Window Motor 93-05 Nissan Altima

Difficulty: Intermediate · About 90 min · Nissan Altima

Replace the power window motor on a 1993–2005 Nissan Altima while securing the glass and protecting the door moisture barrier.

Steps

1. Remove the door panel

   Remove the handle and pull trim screws, lift the switch panel, and unplug its connectors. Release the door panel clips and lift it free, then remove the brace and carefully peel back the moisture barrier for access.

2. Secure the glass and remove the regulator

   Move the glass to expose its regulator fasteners, separate the glass from the regulator, and support it fully with tape across the door frame. Unplug the motor and remove the regulator fasteners, then maneuver the assembly out without scratching the glass.

3. Transfer the motor

   Remove the motor screws from the regulator and release its wiring clip. Attach the replacement motor in the same orientation, secure its screws, and route the harness through the original retaining points.

4. Reinstall the regulator and glass

   Feed the regulator into the door, loosely start its fasteners, and reconnect the motor. Lower the glass onto its mounts, secure it, remove the support tape, and test window movement before reinstalling the brace.

5. Restore the door trim

   Reconnect the switch and verify smooth window travel through its range. Refit the moisture barrier, brace, and door panel, then reconnect switch wiring and reinstall the handle trim and screws.

Check your vehicle’s repair manual for exact specifications and fit.
