I have a problem with my turn lights specifically the parking lights and their side markers. The parking lights will flash correctly if the headlight switch isn't on. As soon as they turn on the dash turn indicator, the light will turn on and not flash. brake lights will work fine, just not the turn signals. Has anyone ever experienced this issue? If so how did you fix it? I've tried new flashers LED specific flashers and heavy-duty flashers. My next thing will be to look at the headlight switch to make sure a contact isn't shorting when pulling the switch.
