Review on Dorman 748-745 BMW Front Passenger Side Power Window Regulator and Motor Assembly: Top-notch Quality for Your Select BMW Models by Alex Jones

I would not recommend this product. If you own an e46 coupe you know that our windows have a feature where they roll down a little when the door is opened to allow the window to clear the panel around the door and roll back up when the door is closed. After replacing the regulator, it is usually necessary to adjust the height of the clips holding the window to the regulator rails. The functionality of the adjustment points is REQUIRED as it is very important that the window is in the correct place where it contacts the seal/top of the door frame to ensure that 1. Not damaging your window when exiting/opening the vehicle becomes. of the door (too high on the handrails) and 2. Water does not get into the car when it rains because the window does not sit properly with the seal around the door (too low on the handrails). The adjustment points on this product are bullshit. The metal is of poor quality and very soft. You can undress her just by looking at her. They become unusable after 1 setup attempt. If you buy this thing you better hope it's in the right place when you install it or you're screwed. If you manage to set it, it won't stay at the height you set it to - it slowly creeps back over time, meaning you'll never be sure if you can safely open the door or not . In addition, the motor is also very slow compared to the motors of the original ESCs. So if you only replace one window, the other window will go down faster. Not as much of an issue as the fitting point issue, but still something to keep an eye on. If you care about your car I would go to OEM or BMW, this thing is made out of cheap materials.
