Hello all!
So I recently had my wiper linkage break on my 1996 940 wagon and I was able to replace it with an old 740 linkage because the part was essentially the same. However, when I got it all set up and running, I noticed the pegs that the wipers attach to rotate counter clockwise instead of clockwise. So I had to attach my wipers vertical, and when I turn them on intermittent they go down then up and hold vertically until their next pass.

Any ideas on what could be causing this and how to fix it?

Thanks!

 

This is the closest I can find to address the issue, running the opposite of what they should has to be a wiring (polarity) problem:
Front Wiper Failure to Park. The wiper motor gets power from two sources. One is from the switch on the stalk. The other is from the battery via the ignition switch, but in series with this path is a switch internal to the wiper mechanism which opens up once per cycle. If the second circuit is functioning, when you release the stalk switch, the second circuit still carries current to the wiper motor until it reaches the wiper position where the internal switch opens. At this point, if the stalk switch is disengaged, the wipers park. If the second circuit isn't working, either because of a faulty wiper park switch (inside the wiper mechanism) or because the external wiring isn't delivering current to this switch, then the wipers park immediately when you shut off the stalk switch, as you describe. First thing I'd check is the wiring. See also the section on repair of the stalk switch.

 

In the picture the 740 wiper transmission is on the left and the 940 on the right. Very similiar - your problem is -

The wiper motor arm (#4 in the left picture) is installed 180 degrees off. Take wiper arms off. Turn wipers on turn off, let them park. Take #4 arm off and put it in the correct position so the arms will be down when parked.

 

This was it!! Rotated that flipper 180 degrees and that solved everything. I had to take everything apart to get to that little guy, but well worth it! Thanks for the help!
