Mopar 68014949AA is the front driver-side power window regulator for the JK. The cable-and-pulley regulator is what breaks when a JK window drops into the door, goes crooked, or makes grinding noises while the motor still runs. Dorman lists its 748-912 regulator-and-motor assembly as a direct OE cross.

Rebuild, repair or replace?
Regulators get replaced, not rebuilt. Listen first: if the motor runs but the glass doesn't move, the regulator is the likely culprit. If there's no sound at all, check the switch and wiring before buying. The Dorman 748-912 includes the motor, which saves swapping it over. A Mopar regulator-only part means moving your old motor. JK doors come off, so take care with the wiring and door check when you have the panel off.
Mopar's diagram shows several related pieces that wear alongside the regulator, including the front carrier assembly bumper (68014955AA) and carrier pad (68014968AA). If your glass was rattling or sitting crooked before the regulator failed, inspect those while the door is open. Rear doors on a JK Unlimited use different regulators: 68018029AA rear driver and 68018028AA rear passenger. For the passenger front, use 68014948AA.
