Postage to Finland shouldn't be that much. You'll need to buy the motor. I'm sure folk sell the same one in Finland as in the UK. They're about £25 here. PM me your email address and I'll send details.
That is the original motor. Yes, that ball on the shaft is a sintered brass bearing that is held on by the spring fingers round the hole. Its rounded so it can wiggle to allow the shaft to run true and freely in the bearing even if the pressed steel endcap is not on exactly straight. Not 100% broken yet, just disassembled badly, but more of a challenge. Try soaking the end of the shaft and the bearing in e.g. paint thinners for a few days. Avoid soaking the copper commutator. Then try gentle wiggling, using e.g. cardboard in the jaws of a pair of pliers to grip it as the sintered metal will crumble under too much pressure.
Thanks @mikedjames for the info. I actually did continue to investicate it and figured out, that as you said. The ball was the sintered bearing and was stuck in the shaft. I got it free pretty easily, oiled it and now shaft seems to move freely. I got the whole thing assembled again, pressed the plates in as they used to be. Its alive now. Then the parking position. Motor seems to stop right away when switch is turned from low to off. It should continue till the wipers are in the "park position" right?
Yes. Turning the wipers off should cause the motor to run for a short while, then stop in the "parked" position.
Good news.. Yes, it runs on using the rotary switch in the gearbox to power the motor to the home position. More technically: The park position on the wiper speed switch connects green (park power) to black (slow) on the motor. The wiper motor gearbox switch makes the green (park power) wire connect to the black/white 12 volt until the wipers are home. Then it shorts the green wire to ground to brake the motor, exactly when the wiper blades are home. If you just stop the power to the motor it can run on for a varying distance depending on the friction of the wiper blades. So VW short circuit the motor to absorb the kinetic energy at the right point, turns the motor into a short circuited generator. Resistance in the motor dumps the energy as heat. If you get the wiring randomised it can blow fuses as the green wire is shorted to ground intentionally and if 12 volts gets connected to the green wire, the wipers run then blow the fuse..
Wipers are working now. Not even that lazy. Park was actually not working because it's pins was not touching the gear. Small thing. I did have a one more hazard and almost broke the white gear. One of the screws on the gear cover is shorter than the others. Mixed them up and put long screw to the hole right above the wire connector. That scratched the gear quite badly. Hope it still hold. Seems like it. Thank you for all your help.
@mikedjames That info about shorting the park wire is valuable. It explaines why I almost burned the motor when I was testing it with another battery and jump connectors. How many things I can actually screw up in job this small... Makes me wonder how the type4 engine will ever work, as I took it apart and back together last winter.
