2004 Discovery, no horn or CC controls

[jastutte]

2004 Discovery with 208,000 miles on it.

On a trip a few weeks back I turned on the Cruise Control only to have nothing happen when I tried to set the speed. I haven't really had time to look into it that much.

Then today when a slow turning, unobservant driver pulled out in front of me, I found out that the horn buttons are not working.

I checked the relay and the fuse related to the horn and both are good.

I'm going to test the horns by directly wiring them to see if they are good.

Assuming they are still good, is the steering coupler/clock spring the next thing to check? If so, can I simply clean the contacts or is a replacement in order?

I think you're on the right track. The clock spring is a good suspect - but I've rarely seen it all go bad at once other than in situations where someone does something real dumb (like not keeping the wheel in place when disconnecting the steering shaft or something else that would allow it to turn too far out of position).

I would definitely attempt to disconnect it and reconnect it to make sure it's not just the connector.

Horns itself tend to go mute. Specially if You do not use them everyday. I did repair from both by connecting fixed 12v and moving adjust screw until contact rust is removed
