850 - headlight wiper motors

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:

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
headlight.)

Replace tt with t (twice!) and remove parentheses to email me directly.
(But I check the newsgroup more often than this email address.)

 

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,
