For the last two days the horn on my car has taken upon itself to start blowing. Not sure what the problem is but I think
it's the horn pad on the steering wheel. The sun heats up the interior enough to expand the soft rubber of the horn pad
causing the horn contacts to touch each other and setting it off. I'm glad it did it during the day and not at night.
I disconnected the battery for now and I'll get at it after the rainy season for the next few days. I have an spare steering
column and I'll switch horn pads. Maybe that will cure it. The only problem is, it's blue so it will clash with the beige.

In my case, the '80 Fleetwood horns started blaring at 3 AM in the middle of winter, on one of the coldest days, close to -18 C.  It stopped as soon as I touched the horn pad.

The internal foam that keeps the contacts apart has degraded.  Drill-out the rivets, then add thin strips of foam around the contact areas, not too much or it'll be too difficult to activate.

Good idea. I will try that.

Thanks Kevin

I removed the horn pad with the attached wire and left it on the seat but the horn still went off in the early PM today.
I hit the steering wheel with my fist and the horn stopped and disconnected the battery again.
What's the problem ??? The horn relay ???

Was the wire still attached when you left the pad on the seat?

Yes, the wire was still attached to the pad.

It sounds like there may be an intermittent short-to-ground in the steering column as regards the circuit that activates the horn relay.  Removing the fuse or relay might be the easiest workaround until the problem area is identified.

Removing the relay is probably the best option as there'd still be some current drain if the short causes it to stay energized, assuming the coil is powered by different circuit/fuse.

I don't know about you guys but I'm shocked. My silly 1990 G van was engineered back in 1973 and they just kept making improvements and ran the model right through 1995 , just like the GM Express vans since 1996. I've been waiting for them to come out with one of these style vans like the Ford transit or transit connect , the big MB cargo  van , here we are 24 years later and still the same - for now. I changed my blower motor on my 1990 in 15 minutes, and the module resistor and the fan switch , more easy work. I'm sure the Express van is likely a PIA but not as bad as Gareth is dealing with.  My furnace guy and his father have Express vans with the commercial chassis and and a huge tool body on the rear. They looked at these new high top vans and what they have is way better.

I had a horn problem years ago on Chester.
It would go off on it's own.
I had a second clue which was the turn signal didn't cancel when straightening the wheel after a left turn.

After pulling apart the steering column down to the signal switch I found the broken piece of return spring floating around in the column and shorting out the horn circuit. I removed the piece of spring and it's been all good ever since.
