Dash Instrument and Tail Lights not work

Without looking at the car,my best guess would be that it's a bad headlight switch. Here is a guide t help test the switch with the tail light wiring diagrams so you can see how the system works, also there is a tail light relay that needs to be checked.

Electrical problem

replaced all fuses, but have no tail lights. Brake lights, turn signals and backup lights all work. just no marker lights. Is there a relay somewhere that I am missing?

Hi aiob15,

Yes, they could be related.

Check the taillight fuse and also the license plate light bulb installation for possible shortings.
