Steering wheel radio buttons confused.

Been playing with the controls on my recently acquired 4.6 vogue & have a proble with the steering wheel buttons. The cruise control works fine, but...
The volume buttons on the R/H side do nothing. The mode button on the L/H
side does nothing, of the other 2 buttons on the L/H side the top one sounds the horn and the bottom one reduces the volume. Can anyone help please, the radio does work normaly from the facia controls. Thanks very much.

Wagoner,

I had this problem, as well as the radio sometimes going into "MUTE" mode when I pressed the volume buttones.

It turned out to be dirty connections in the steering wheel buttons.

I was going to take it to bits, but after a bit of use, it seemed to clear itself.

Hope this helps!

Thanks very much garioch43, I will keep using the buttons & see if it clears. Does anybody know if the sw buttons link directly to the radio head or do they go via a computer or fuse box somewhere?

they go straight to the radio

Thanks very much clutchdust. Looks like I will have to take it all apart & have peep in there. One of those buttons causes the horn to sound every time so something must have got crossed up.
