my 3rd gen horn is not working..but sometime when i'm taking turns,it works ..what do u guys think it could be??

 

There is a wiring harness under the driver side front wheel. Jack the car up and see if the wiring harness has gotten chewed up.

Also check the wires to the horn itself.

 

I'll do..many thnx..

 

Just looked @ the wiring harness,looks good to me...think I'll have to go buy my self a air horn & put it on..thnx guys..

 

I'd guess that the flat terminal ears may be corroded. This is what has happened to my 87 GXL. I removed the wire connectors from the flat ear terminals on the horn itself, sanded the ear terminals a bit, tried to get in the connectors a bit, too... (I am sure some electrical cleaner would work well for those.) Then reinstalled the wires to the terminals.

I don't know how the horns are on the FD, though. I just figured they'd be pretty similar...?

 

My horn began blaring one day when I was working so I disconnected the horn. Might have done the same thing. I have seen a thread on this exact problem, it sounds common.

 

Did you check the air in the tires...

Anyway, since it works when you turn corners, it's the little electrical couple that joins the wheel to the column. I don't know how it works in a 3rd gen but in a first gen, there's two plastic pins that need to be aligned with the holes in the steering wheel. The white two pinned coupler usually has a graphite pin that rides on a copper ring that's connected to the horn relay.
Have you recently removed the steering wheel? Does your model have an airbag? If it does, it complicates things as it needs a coupler to activate the airbag.

Take the wheel off gently, you might want to disconnect the negative battery terminal. Then check how the wheel transmits the horn (and possibly) the air bag pulses to where they're supposed to go. On a 1st gen, if you don't line up the two plastic pins, the horn stops working altogether.

Just ensure that whatever couple it uses is moving with the wheel like it's supposed to. You could temporarily connect the negative terminal and then ground the lug on the column side of the column and see if the horn works; be 100% sure the airbag is not connected, since it's in the steering wheel, if the wheels on the floor you should be OK although I just thought of something bad. What if you ground the wrong thing and it blows the passenger airbag?? Does it turn freely? If aligning things fixes it, don;t forget to disconnect the negative terminal before you button everything back up. Is there an indicator light that says anything about the airbag? If not, you're kind of taking it on faith whether it works. Then again, it might not even have an airbag so disregard mention of them.

Good luck.

 

^^ i agree since nothing else is really moving/changing position (as far as wiring is concerned) when your turning. I would look into the steering wheel coupling mechanism.
