Right know it's more where to look. looking for the horn relay which should be next to the radiator behind somethin? and i can check the wiring there. my problem was a short that is making the horn sound all the time?
will get back to you guys if it pans out, gives me a few more things to check if i can get to the horn relay that is about half way from battery to steering wheel, i think the wheel is o.k. done that before. so will check the voltage reg. and horn relay next.

Re: thanks

I think there is also a relay 101 somewhere (in the electrical stickies perhaps). If you're new to relays, knowing how one works may help you. In summary a relay is a coil of wire that creates a magnetic field to operate a switch. The coil requires only a few hundred milliamps to operate, but the switch can handle 10s of amps.

In a horn relay setup, the relay coil gets it's power from the relay bus-bar. The horn button provides a ground for the relay coil. When you press the button, the coil is energized and closes the switch inside the relay to operate the horns. So if the horn button wire was grounded somewhere or if the relay switch contacts were stuck closed it would cause your horn to sound all the time. A wiring problem at the horn relay could also do it.

Re: thanks

Disconnect the "harmonica connector" on the steering column. That'll at least tell you if the horn circuit is grounded in the column/steering wheel or bulkhead/engine compartment. Be careful putting it back together....the little terminals like to push back out of the connector.

Re: Thanks

o.k. i think i get what your saying disconnect the spring in the steering column and if the horn still does not go off then the ground is not in the column? i found out that the relay is in a relay and fuse plastic box opposite the battery the horn relay is just a square pronged cube, know all the relays where the same number on them except the abs vI one so i put a different one in and had the same problem so it is not the horn relay [i think]. when i put that connector which is a black tube with a spring in it should the spring be all the way in the black tube? is that what you mean when you say that the terminal pushes back out of the connector . because i was turning the black tube to hook the first knob and there is two knobs on the black tube know that you say that i think i'm not pushing the black tube in enough and the short is right there . I'll have to che4ck that again .

Re: Thanks

Swapping relays with the same part number is an excellent test. You know now that the relay switch terminals aren't shorted internally at least.

Steiner was talking about disconnecting the harmonica connector. That is a semi-circular connector located below the stearing wheel on a 1st generation Camaro. The point is that separating it isolates the column. If the horn still sounds, then the short is somewhere between the column connector and the horn relay - not in the column itself (unless you have really bad luck and it's shorted in two places).

All the business about the connector pushing pins out is also associated with a 1st gen harmonica connector. The pins are made in such a way that they can push against each other instead of mating. The result is the pin pushes itself right out the back of the connector instead of mating. Just beware of this.

Personally, I have no idea what vehicle we're talking about here, but I presume it isn't a 1st gen Camaro. When you talked about swapping relays with the same part number I presume you have a different vehicle. BTW: What the heck is this thing we're pondering?

Ha ha. I'm with you....especially since the last post said something about the ABS fuse. Mine used to have ABS, but without the "lock" part.

LOL

I think you meant to say "Harmonica Connector".

Your 95 will likely be much different, but the same idea applies. See if there is a connector (or connectors) that separate your horn wire in the column from the rest of the under-dash wiring. If the horn stops honking then you've got a shorted horn wire in the column or perhaps in the button assembly. Just watch those air bags. There is a disable procedure that involves disconnecting the battery for 3 minutes, and then disconnecting the air-back itself. You don't want that thing blowing up in your face while you're noodling around

Re: Thanks

You don't have a boogarlar alarm in that car do you? They often connect with the horn circuit. Perhaps the alarm unit has shorted out or a botched wiring job has engaged your horns.
