2010 BMW 335d Turnsignal, cruise control, wiper stalks on steering column dead!!

Hi guys I just purchased this nice little 335d bmw and i got it cheap because all three stalks on the steering column are dead, there is only one button on one of the stalks that does anything and its the message center button that sets time and date etc.. I have a maxisys elite coming today and was wondering where i should test or start to look, nothing on the car has been modded or taken apart, im assuming all these column wires go to some modules and am suspecting a ground issue?
