Hi I have noticed my truck (2000 Blazer Trailblazer ) has had some wiring issues. I originally have put led plug n play lights in. I noticed that my horn would only do the high side and my right turn signal light would show on dash, so I put oem lights back in. Made no difference. Now my exterior and interior lights are flickering. I didn't know if anyone has had this problem or has a solution. Even a wiring diagram would help.
