The horn stopped working, have replaced relay, fuse, there is no power going through the wirtes to the horn or to teh horn s themselves. The wsitch in the sterring columb is working fine - got it tested. what else can be causes it to not work? We also cannot find any wire diagrams that list the horn - have searched all manuals

SOURCE: 1995 Buick Regal- No Fuel pressure due to no power to relay

Best place to get that may be your public library.  Many have the Mitchell electrical manuals in stock.

it seem that all your vehicle have electrical problems. is better to make a electric inpection to the dealer.
