Okay so my rear drivers side taillight doesn't work.

here's what does work on it.

Turn Signal, Brake Light

However the regular red running light and the reverse lights do not work.

I checked/replaced both bulbs to no avail.

I was looking at the wiring diagram and checked Fuses 32 and 19 under the dash both are in working order and if they weren't other lights would not work.

When taking the tail light off Nothing looks to be bad. the bracket to the harness on the taillight is rusty but unplugging and inspecting the harness yield nothing alarming to the untrained eye I have.

What should I be checking to get these working? It sucks because I am just playing pullover roulette when I drive at night and one of my taillights is out.

 

It sounds like a wiring problem. If you have a test light, check for power and ground on each light socket, and then also at the harness plug with the tail lights harness unpluged.

If you have power and ground and the harness connector, and nothing on at the sockets, then it's the tail light harness. This is a very common problem on hondas. They rust out and stop working. I can not tell you how many I have changed on Integras, civic, rsxs.
