The Ace

I know that the solution might be obvious, but just to make sure: in my gen2 Turbo II the lights control is semi-broken, and I am having difficulty changing between low and high beam. The problem is that if I am at low beam, and I hit a bump, a hole or something that'll make the car rock, the lights will go into high beam (they will go back and forth between low and high like some contact is fried). Is it just the control which needs replacing (the one on the left of the steering wheel), or some wiring, plug, fuse or contact needs also fixing ?

Problem fixed: one of the relays that are on the bumper what almost off its hook. Took it out, took a look, reinserted it, works just fine...
