Yes, there is a relay. With the intermittent wipe/washer etc it is all quite complex. I have a wiring diagram for the 1999 (European) Passat but I expect that your Mexican version is nearly identical. Post a contact email/hotmail address and I will upload the pdf file for you. This bulletin was originally from a Russian site which has sadly disappeared. Regards
Yes there is also relay for this. I had the same problem and found that the relay was in the wrong location, fixed the problem right away.
