Car back from body shop - horn buttons don't work

[MuRCieLaGo]

Hi guys,

I just had my 1991 back from a respray. They forgot to connect both hood lights - easy fix, I just plugged them. However, both horn buttons don't work. Both horns are connected.

They were both working fine before I sent the car out.

But it does work when anti-theft engages.

I removed the air bag and tried to cheat around to get the horn buttons working, without any luck.

Am I missing something?

EDIT: I removed both horn buttons, played around a little bit... And now everything works fine. I do not understand why.

When I got my 91 two years ago the horns didn't work when pressing the horn. I set the vehicle alarm and the horns worked. I went on good ole YouTube and found a video on the C4 horns. All I had to do is remove the buttons by pulling them off. To remove them you pull them towards you by prying them back at the top of the button. Then underneath you will find a copper strip and under that strip is the contacts. I used some fine sandpaper to clean the contact area under the copper strip. It has a little pin in the center that makes contact. Just be careful removing the horn buttons. They have plastic poles that press against the copper strips. If you break them you will have to get new buttons. They are easily found new and used on eBay.

Alright that's the video I watched. I broke a pin on the right horn button while removing it, I'll have to buy some epoxy tomorrow.

I'm a bit skeptical though, both horn buttons quit working at the same time? Hmmm!

Thanks for your help!

I did repair a horn button with JB Weld. I built it up over a few days and then filed back in the notch/hook that had snapped off. Or one can spend 35.00 on eBay. I like the challenge of being cheap!

I was a bit skeptical at first. My contacts didn't look at all corroded. After a few passes with the fine sandpaper it was working fine. Now that I recall I think both started to work after I did one side. I still took the other side apart and hit it with the paper. I repaired my console lid button after it broke and I use it as a spare. I used gorilla CA and you can't really see the repair.

So, as expected... Problem is not from the horn buttons. I still sanded the contacts with 800 grit. There's something wrong with that cable I'm pretty sure. But I don't know how it works. I've seen something about a broken plastic retainer?

Superglue fixed my right side horn button...

The connector has a ‘tab’ on the side, which should insert into the ‘key way’, once it bottoms out in the receptacle, gently twist it clockwise so the nub or tab goes into a retaining slot - similar to an automotive bulb.

Alright that's the information I was looking for!

I found the problem. The clip is broken. The broken piece was still laying there when I removed the steering wheel. I'm confident it could be glued, if only I knew how to remove it... Do you guys think it's safe to remove that retaining clip? The big sticker kind of scares me.

Can you use a set of tweezers and carefully gel superglue it in place?
