i've been having issues with my drivers side headlight for months now.

before i did the 99 conversion on my car, the drivers side headlight was always brighter than the other.

one day i rear ended someone and decided to do the conversion, i needed a new core support etc. i also changed all the bulbs and im still having the same problem. except now the the drivers side turn signal doesnt turn on. it only turns on when i make a turn. but it blinks really dim and really fast. (the driver side rear also blinks fast but not dim)

help me out guys, is this a wiring issue, a fuse issue, what?
