The running light works fine but when I signal only the back signal flashes. I changed the bulbs and checked fuses. I took apart the socket and all looks good. Any ideas?

Thank you

Hello, the next check would be using a test light to see if there's power up there, with the test light connected to battery negative and turn the blinkers on, test light should flash just like the blinker does. A test light is cheap and good to have, you can purchase one at your local auto parts store.
