My brake lights and turn signals work. But when I have my headlights and parking lights on (nighttime) the taillights don't go on, but still work when braking/signalling.
My service engine soon light in the dash is also on...

Anyone come across this problem? Figure it has to do with wiring but wanted to check in before I take the dash apart.

Appreciate any insight. Thank you much.

 

Welcome to the forum...

Sounds to me like a bad ground somewhere in the system., rusty socket, wire, fuse could even be the common ground that's attached to the frame...

Or ..It could be a faulty Multifunction switch.. (its in the steering column)
This was the problem with My wifes vehicles a few years back...

I'm sure someone here is better with wireing and may have a better idea as to whats going on and how to fix it.

Just be sure to let us know what it was causeing the issue as well as what you had to do to resolve it!
