Wiper wont turn off

[passatmann0]

Hi, my wipers have decided to stay on permanently, 2002 130 tdi sport, speed 1 and 2 work as usual but still stays on speed 1 when in intermittent and off positions, car has rain sensing wipers and the relay no 192 does wipers and auto dipping mirror, with the relay removed the wipers don't work at all, I have managed to bypass the relay to get the wipers working on speed 1 and 2 so don't have intermittent or self park, it is the same with a second hand relay fitted, just wondering if anyone has any ideas or a wiring diagram relating to the relay so I can trace the wiring to rule out a wiring fault, got another relay coming just in case
