    You would think so. I change the relay and also removed the air bag with the switch and same problem.

    Sounds like either the horn relay or the switch in the steering wheel is stuck closed.

Take the horn button assembly apart--there should be only one wire there (goes to the horn relay) and not be grounded. It goes to the insulated metal part that grounds the plate when button pushed. Unfix the grounded wire and see if horn is quiet. You may need to replace that wire if it still sounds.

Horn not working on 2002 Buick Regal, check fuse and that's not the problem. Any ideas???

you need a test light to see if there is power and earth going to the horn when the switch is pressed,, if the live and earth are present you need a new horn if they or one of them are missing you will need totrace back from the horn to find either a broken wire or a faulty switch ,,, hope this helps

2000 buick regal blows high fan fuse as soon as it is put in with car offf

I would disconnect your blower motor resistor then try fuse again, if it does'nt blow then it is either blower motor or resistor,these resistors are common for going bad/and or blower motor. Good luck let me know if you need more info or if this didn't fix it, I will research it more for you

My horn stopped working on my '99 Buick regal.I went to check the fuse but it's not on the fuse diagram.Which fuse is it?

If the fuse is not in the under hood fuse block look on the passengers side instrument panel.You should see at the end of the i.p. when you open the passengers side front door.Hope this helps.Good luck.
