Horn doesn't work over 25 mph

I have a 2004 TB LT EXT with 2500 miles on it. Has anyone heard of the horn not sounding when press when you go over 25 mph? My wife noticed this today. I plan on checking it out myself too.

thanks.

Now that's a new one. Can't imagine, but maybe the body systems control computer is connected to this too? Do your door locks auto lock at around this speed? Dealer service can connect a Tech tool to the computer and operate just about everything on the vehicle. Why they want to do this, I can't guess.

thanks for the info. I tested out the problem and found that you have to press the horn pretty hard to make it sound. Possibly the conacts aren't big enough. who knows. .......
