hi there, i think my wiper motor is malfunctioning ('84 325e). i'm just wondering what the BMW part number for the motor is, and if it is the same for any other models/years out there. i'm going to look for a replacement at the junkyard, but i haven't found any exact model matches yet. basically, is the motor the same for all e30s? i think there are some 318's and 325i's out there that i can use, but is the motor going to be the same? if so, what range of years can i use?
