I was recently involved in a rear end collision (my car being the one that got hit) and when I got hit my whole head unit for my radio came out. Ever since then both turn signals, my instrument gauge, AC lights and gear lights all flash at the same time. I’m assuming something somewhere is loose as it doesn’t happen consistently but whenever I go over a bump in the road all of that will start flashing and a tick will come from the instrument gauge. Does anyone have any idea as to what might be causing this? I know it’s not my hazards as those still work.
