check fuse number 5. It should be a 15 amp blue fuse.
If all else fails pick up some rain-x. I ran that for months once when I didn't feel like changing out a wiper motor. It does work!
I'm currently working on fixing the wipers on my Jetta also but they currently work on high setting, and when they want on slow, but no delay or park etc.
There are a couple threads on here you should find by searching problem with wipers or not working etc. That may be helpful.
I know its a fairly simple system and if your fuse is good the next places to check are the motor and then also the stick on the steering wheel where it mounts.
Sorry I can't advise where to check exactly as I am figuring that out tomorrow but I would start by removing the cowl cover/windshield seal that covers the wiper motor and check for voltage to the motor to confirm if it is good etc (be real careful removing the cover and th clips that secure as both are easy to break etc) and then if no voltage work your way back.
I know my is likely different than yours but I put a good coating of rain-x on anyway just in case it decides to crap out at the worst time lol
Well this is interesting.
Totally by accident I got the wipers to work on slow setting, but still need to permanently correct the problem.
Must have had them in the on position instead of park etc and when I slapped the wheel after being cut off the damn things started working lol.
Seems that something is loose in the column and when you shock it the wipers come on in slow position. Still not anything in intermittent setting though.
Maybe its the wiring in column or even the wiper stick?
Fun, fun, fun!
I will be pulling apart the column soon as time allows and hope for an easy fix, and also that jettadude may get success too (though it seems he may not be following anymore lol).
Have to admit dealing with all these VW gremlins is getting old
