It works!!
Many thanks for the great help!!

I restarted the work from field one.
- Identification of the DR 3 wiring -> did it correct the first time
- Identification of the PRS7 wiring -> did it correct the first time
- Connected them together according the provided wiring (many thanks to Mongoose) -> same as I did it based on other diagram

And it did run!
It seems to me that the PRS7 contacts were probably corroded. At least after many switching attempts it started to work on all three positions.

What I previously identified (direction change) was the change between Normal and Park. The motor did never run on Fast….

The wiper wiring (with original rotary switch) is explained in my "Wiring Primer", page 21.

I’ve still an issue with this combination..

Most of the time it is working fine but from time to time it happens that, the wiper motor is blocking and making some noise. This happens always after the switch gets moved from one position to the other. (different positions)
The only way to solve this is removing the 12V and switch a few times prior to reconnecting the 12V.
This is ok on the table, but not fine if it is mounted inside the engine bay/ dash.


Does one of you have seen the same issue and can something be done to prevent this.
