My vehicle's instrument panel has been failing: you simply open the switch and the needles start moving from side to side, even sometimes colliding into one another. What I do is to hit the dashboard a bit and they either mend or stop. I was thinking that may be it was simply a poor contact or a short circuit, what do you think about it? Thanks.
With a magnifying glass I was able to identify some welding points in the instrument panel that were damaged (5). I've welded them again and the problem was solved.
