would be a big help?

If you told us what year/model you are talking about

Pictures of useless button are helpfull.

Sounds like you mean blank.switches? They're provision. They may be used in higher or foreign spec vehicles, such as for heated seats. Or beacons on the roof of estates/emergency vehicles, or just additional spec - pretty much all cars have provision for additional buttons.

Unless you mean they're proper buttons and wired in, bit you don't know what they do..?
