Re: Horn, Radio and drivers footwell light!
Check all your fuses, this is the source.
Even if they all look OK, replace the ones that are listed as controlling the systems that are going haywire and this will probably solve it.
Apparently there is a bit of a terminator thing that goes on if a fuse goes, and the system tries to reroute through other fuses. Sounds great but never works and usually causes the other systems go nuts too. I have had this on a GTV, and changing the relevent fuses fixed it.
