I have a 1994 850 whose horn would not stop blowing last night. I pulled over and took out the fuse as a temporary fix, unfortunately it seems that fuse also goes to the windshield wipers. After speaking with a friend he suggested I disconnect the ground wire for the horn to make it stop so I can use my windshield wipers. Problem is that friend could not tell me where the wire is, any insight? I just need a temporary fix until my car goes in for scheduled maintenance (timing belt, cv joints) at the end of the month. Seeing that I am in Chicago, it could rain any second so I need those wipers... Trent
