Wiper has lost its mind!
So i thought the relay 201 821 00 47 was the combination relay that controls wiper/defroster/sunroof i replaced it as my defrost didn't work, even though it lit up.. still don't know if my defroster works, but today, the wiper is on the "off;0" position, and still goes on the slowest setting its driving me nuts, and the fuse for it disconnects the windows.. so im forced to take the fuse in and out everywhere i go 
did i buy the wrong relay? for the convienence relay? (i tried 3 different relays, same one, still same issue.. is it the combination switch?)

tried 3 different relays, original, one from junkyard, one from my sedan, turns out my sedan has a facelift relay, and it works fine..
tried cleaning the combination switch connections with electrical cleaner, but its being a brat so i need to pull the whole steering wheel out, and swap it!
