2005 S60 turn signal/ radio control problem...........

[Dawnpatrol]

I have a 2005 s60. The problem is that the turn signals will not work at all and the radio control buttons on the steering will also don't work and the turn signal lever also has the drivers information switch on it and that doesn't work so i think the problems are all related. i think it's a module / relay in the steering column but not sure. Does anyone no for sure?

Thanks, Mike
