thanks so much,
i knew it was something simple and everything pointed to it being a fuse but i never thought to clean the contacts! i had decided in my mind (stupidity) that it must be a relay.
anyway, thanks once again, i'll try the search facility next time.
i see you have a 911, i have an '82 SC. unfortunately it's due a gearbox rebuild......ouch! but it'll be worth it, i intend keeping this car a long time and the rest of the car is pretty mint.
like yours, it may be old but it still turns heads, and even at twenty one years old the finish on mine looks better than any modern car.
