I am wondering if this is a wiring issue or something, but my turn signal and brakelamp went out the other day, yet the running light is still functional.

Checked the fuses, they look fine, the front turn signal is functional.

Any ideas? I was thinking maybe flasher, but that doesn't seem like it would control the turn signal and the brakelamps

I think the turn signal, and brake lamp are the same filament in the bulb, running lamp is separate, try changing the bulb.

 

Sorry, forgot to mention that I had changed the bulb and the issue is still there.

 

Check for power/ground at the socket. If you have a trailer harness, check where it hits the rear harness. They are notorious for causing issues.
