Windshield wiper intermittent setting doesn’t work. Wipers do park and work on continuous wiper settings
Hopefully you guys can help me out, I’m honestly completely lost on this strange issue that I haven’t been able to figure out on my 1981 924 Turbo (same as early 944)
As the title says, the intermittent wiper setting doesn’t work at all. Both continues wiper settings do work, and when switched off the wipers park themselves properly. Also when pulling the wiper stalk for the washer function, the washer sprays and the wipers turns on for one full sweep and park themselves properly.
What I have already done/checked:
Replaced the intermittent wiper relay.
Disassembled the wiper stalk and cleaned all the contacts. Used a multimeter to verify continuity and each setting on the stalk corresponds to a pin, so I assume the stalk works.
Took the wiper motor apart and cleaned all the sliding contacts inside and verified continuity across them to their corresponding wires.
I am honestly out of ideas what this issue could possibly be. Last thing it could be is a broken wire or a bad ground, but I cant find the proper schematics for my car anywhere (EU model, 1981)
I hope someone could help me figure this out!
