Its under the passange side dash... Its a black box with two plugs in it...
The fuse and relay panel is under the dash on the drivers side near the left kick panel.
I have '92 Cabriolet and just had this happen to me. It was a good sized relay under the dash under the glove box - pretty easy to get to. This relay also happened to fix an issue with the power sprayer for the windshield which wasn't working. I'm not a mechanic so this is only observation - don't know if the relay controls both. Bought the relay at GermanAutoParts.com for about $130.00.
