Bmw 325 window regulator with motor installation

chances are, the motor is fine. the regulators break all the time though. You can install it yourself with a little common knowledge. First obtain a new regulator for the respective door from your local dealer. To begin, remove the door panel. use a small screw driver to pry off the wood trim at the top portion of the door panel starting from the rear and moving forward. then pry out the small cover by the door pull as well as the 2 covers underneath the armrest. use a T-20 torx driver to remove the 5 hidden screws. then pry the door panel off of the door being careful not to ruin the clips or tug on the wiring. set the panel aside.
now you will need to remove the side airbag (if applicable)using a 10mm socket. release the locking tab on the plug by prying it up approx. 1/4 inch, and then pull the plug out of its connector. be careful not to turn the key on with this unplugged or the airbag light will be tripped on. if you must , re install the plug so that the computer can "see" it.
Now remove the vapor barrier using a razor blade. be careful not to rip it. once the inside of the door is exposed you should remove the 3 T-30 torxes on the window motor. then tilt the motor out of its bracket and remove it. you may have to pry at it depending on how tight the cable tension is. Now that the regulator is left in the door you have to remove it.
lift the window by hand up in the door until you can see the two 8mm screws attaching it to the regulator through the 2 rectangular slots in the regulator arms. if the window is jammed down and will not move, use a pair of dykes or wire cutters to cut the cable to free it up. now remove those 2 8mm screws and push the window back and up into the door where it goes when you roll it up all the way. now remove the 5 10mm screws holding the regulator to the door.
install the new regulator into the door and bolt it in place. pull the window down and install the 2 8mm screws. re install the motor, vapor barrier, and airbag. then press the door panel back onto the door and bolt it back in, and finally install all of the covers.
