My rear running lights stopped working. Brake and turn are good. I replaced the head light switch and turn signal switch already. My backup lights stopped working too. I can't figure it out

Just might be the bulbs, odd as that might seem that just the filaments for the running lights went bad at the same time. One other possiblity - single filament bulbs where the two contact (two filaments) go.

I can't second this enough. I went round and round with a similar problem for far to long. Turned out the PO used single filament bulbs.

Since both rear running lights & B/U lights go to rear thru same harness, follow the harness to see if any corrosion or damaged wires.
