Hi!
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:

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...

Bye,
