Hope you get it sorted, had the same thing happen to me in the summer ( no cooling fans or indicators ).. Mk4`s were prone to this relay burning out, as with the fuel pump relay under the dash..

It`s an easy fix though, and always worth carrying a couple of spare relays ( from the scrap yard ) just in case.. mine packed up on one of the hottest days of the year, not the time to lose your fans!!!!
