Finally got my XJ back on the road today after redoing the floors. Almost got side swiped though b/c i was boxed in and couldnt move, and apparently my horn doesnt work anymore so i had to slam on the brakes...anyways, i dont want that to happen again so here is what happens. Anytime i first start it and drive it, if i hit the horn, it beeps for maybe 1/2 a second and then shuts up for the rest of the trip, if i shut it off and drive it again later it will do it again for half a second but thats all i get. What could this be? I searched and found stuff about the relay but that didnt sound like it b/c technically still works but only for that half a second, any ideas? Thanks all.
