The dash console on your BMW E36 is used to house the instrument cluster, radio and heating controls. If the console becomes damaged, the components which it houses will no longer work correctly. If it is the instrument cluster that becomes damaged it can also be a serious safety issue when on the road. The best thing to do is to remove the console from the dash in order to have the parts repaired or replaced.
