non intermittant 200tdi wipers

Sorry for the long title but ..........I have a 1994 200tdi the wipers work fine in first and second speed but I have no intermittant wipe. my questions are 1/ where is the intermittant wipe control unit and 2/ does anyone have an wiring diagram/s for my car and if so will they private message them to me .
Regards Harddrive

Some models dont have intermittent settings on them while the stalk looks the same.

I had a car like that once and I made my own intermittent wipers..
I turned them on..
pause...
I turned them off..
pause...
etc
