Where can I find the proper window motor for my car?

[irocz0r]

Hello guys. My passenger side (right side) window is inoperable. The switches aren't the problem, so I'm going to try replacing the motor.

My car was built before 7/87, making it an "early 87" car. From what the previous owner told me, this affects the window motors.

Can someone help me find the proper window motor for the right side of an early 87 sedan? I've tried searching but haven't gotten a confident answer.

P/N is 51 33 1 370 840 (discontinued) or 51 33 1 386 988 (latest). This is the same motor for sedan or coupe, front or rear, right side only. E30s built before 3/88 are considered "early" models, those after 3/88 are "late".

Before replacing the motor, check to see if there is current to the motor. Wiring failure in the door hinge area is common in 20+ yr old cars.
