You need to isolate the problem,,,,,,,which lights stay on? turn, tail or brakes,,,,,the rear only or all 6 which includes the 2 dash ones,,,,,,lots of ways to check it out,,,,,,,unplug brake light switch,,,,pull tail light fuse,,,,,,pull the flasher out,,,,,,we can fix this,,,,,just provide some clues so we know which way to go instead of a 100 guesses,,,,,,,,do you have a 4 way flasher switch which is on?
