I checked the fuse it's good and I replaced the bulbs, still nothing. When I checked the turn signals the driver side both bulbs light up, and on the passenger side only the bottom bulb lights up. Same if I turn on the hazard lights. Could really use some guidance. Not very mechanically inclined when it comes to wiring. Thanks for the help.

Good afternoon,

I attached a diagram for you to view.

Check the orange wire at the switch for power. Make sure it has battery voltage.

Also, check the dark green wire at the rear socket on the right side for power. You may have a bad socket or a wiring issue.
