Difficulty: Intermediate · About 75 min · Nissan Maxima

Replace the front power window regulator on a 2004–2008 Nissan Maxima while securing the glass and restoring the door moisture barrier.

Steps

1. Remove the door panel

   Release the handle and pull trim, lift the switch panel and unplug it, then remove the panel fasteners. Lift the panel away, disconnect the latch cables and courtesy lamp, and peel back the water shield carefully.

2. Secure the glass and remove the regulator

   Lower the glass to access its mounting bolts, separate it from the regulator, and tape it securely to the door frame. Unplug the motor, remove the regulator and track fasteners, then guide the assembly out through the access opening.

3. Install the replacement regulator

   Feed the replacement assembly into the door and start its mounting bolts by hand. Reconnect the motor lead, secure the regulator and track, lower the glass onto its mounts, and tighten the glass fasteners to the vehicle specification.

4. Reinstall and test the door

   Reconnect the switch temporarily and verify smooth window travel before replacing trim. Restore the water shield, reconnect the latch cables and courtesy light, then reinstall the panel screws, clips, and switch bezel.

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