    I have Volvo 850 from 1997, and its right headlight wiper motor is
    faulty. My friend was visiting a couple of hundred kms distant scrapyard
    and brought me both left and right headlight wiper motors for a really
    small price. I was told in advance that one is faulty, but they didn't
    know which one. And I was unlucky - now I have two broken right
    headlight wiper motors :)

    Does anybody knows if it's possible to use healthy parts from the left
    motor, and make the right motor work?

    Here are the part numbers and pictures of both motors - right
    0390206926, and left 0390206927:


    Thnx very much!!!

    I've only ever taken a right motor apart (why always right), but as I
    remember, all of what I'd consider "failing" parts would not have been
    different left and right. What's wrong with your motor(s)? Mine worked
    very slowly for about 1/4 sweep, then stopped until power was removed
    for a moment, then it would work slowly for another 1/4 sweep. The
    problem was with a small plate that was designed to raise resistance
    when the motor was on for a long time to prevent the motor from
    overheating. (Like would happen if the blade was frozen to the

    Because it's harder to replace :)
    That's what I think and hope for :)
    The one in the car is only making constant buzzing sound and won't move...

    Do you have any idea what that might be?

    And the other I just bought looks fallen apart... The shaft is loose.
    I did't have time to connect and test it yet.
    Ufff, I know how bad it sounds when I forgot that the rear wiper was
    frozen to the tailgate glass...

    Thnx, I'll try to fix it when I find some time by donoring healthy parts
    to the broken one, and will post results here...
