When a slow or stuck door window comes down to a worn-out motor, the Dorman window motor, part number 742-503, is the window lift motor that drives the regulator to raise and lower the glass. It fits many vehicles, among them the 1993-2001 Nissan Altima, 1995-1999 Nissan Sentra and 1998-2004 Nissan Frontier. See the Buyer's Guide tab for the full list.
Dorman designed this window regulator motor to perform like the original equipment motor on the listed applications. The catalog lists it for the front left, front right, rear left and rear right positions.
- Direct replacement: Built to perform like the original equipment motor on the vehicles it is listed for.
- Ideal solution: When a factory motor fails from damage, fatigue or collision impact, this motor is engineered and tested to help bring back original equipment operation.

If a failed motor is the reason your window is slow, stops partway or won't move, this motor replaces it. A faulty switch, fuse, wiring or regulator can cause similar signs, so diagnose the cause before replacing the motor.
