Hi I have a 99 Dodge Dakota sport. I have been having major issues with the lighting. First issue was no headlights I found a ground disconnected under the steering column ( presumable from the previous owner) after reconnecting the ground wire the headlights worked fine. Then my second and still main issue was the turn signals. With the headlight switch in the off pos the turn signals seem to function normal unless u step on the brake then they stop working. Also if you turn the parking lamps on or headlights from the switch the turn signals will no longer function. Also when stepping on the brake pedal the check engine light and a few other lights will light up on the cluster, also the airbag light under the radio will light up and the interior dome lamp will fill. I have disconnected the trailer wiring harness, replaced the flasher twice ( the one in the fuse box inside the truck) I have replaced and checked every build through the entire truck with no luck. Anyone else have this problem or has any advice on fixing this lease help!!!! Thank you in advance

 

You have a bad ground somewhere.... finding it is going to be the fun part.

 

I have managed to track my issue down to the brake switch. There is a white and tan wire there that feeds the brake lights. So I'm assuming that my issue is some where between the pedal and tail lights.
