So this is my story on my 1990 BMW e30,I crash the car brought it to a well known body shop front end was hit so I got all new part,the problem is that I had three pin head light adapters for my old broken headlight I went and purchased 1989 oem project headlight that had two pin adapters,I cut the wiring off the two pin headlight and gave it to the body shop they installed them but everytime I put my low beams on the right signal light will be stuck on the dash I looked at the tail light and the signal light is stuck on it doesn't flash even when I try to do a right signal what could cause this
