Yesterday I changed the stalks from my mk2 (1990 gti 8v) to the mk3 stalks. Everything seemed to work great, except I noticed that my rear wiper wasn't working (it works 10 minutes before I swapped, I checked everything first). The washer is working, but the wiper wont move. Could I have forgot something, there is two wires (red and black) off the button, on the washer stalk that isnt plugged in, do they go somewhere? Any help would be appreciated.
