Difficulty: Intermediate · About 45 min · Nissan Altima

Replace a Nissan Altima window regulator with the glass supported, then confirm smooth travel before resealing the door's moisture barrier.

Steps

1. Remove the door panel

   Release the switch and handle trim, remove the panel screws, and lift the panel away from its clips. Disconnect the door cables and peel back the moisture barrier carefully.

2. Support the glass and remove the regulator

   Loosen the glass retainers and raise the glass by hand. Tape it securely to the door frame, unplug the motor, and remove the regulator and track fasteners.

3. Install the replacement regulator

   Guide the new assembly into the door and start all fasteners by hand. Reconnect the motor, lower the glass onto the track, and tighten the retaining bolts evenly.

4. Test and reinstall the door trim

   Cycle the window through its full travel and check for binding. Restore the water barrier, reconnect the handle cables and switch harnesses, and reinstall the door panel.

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