Review on 🚗 Dorman 740-478 Front Driver Side Window Regulator: Perfect Fit for BMW Models by Saber Spencer

Make sure you tighten all mounting screws before testing the power (i.e. using the switch to move the bracket up and down move). If you don't do this, the holder will stick to the frame. You do NOT want to flex the frame for the wearer to clear the frame (I'm doing this like an idiot - don't be me). Once the mounting bolts are tightened, the frame becomes a "loaded element" (not sure if that's the correct terminology) and the wearer should release the frame. Otherwise the installation was easy, you just have to move the old engine. to this frame is easy, just pay attention to where the bolts go and the alignment of the motor on the old frame. If your old motor breaks down, you will also need to buy a new motor - it does not come with the motor.
