I have put new bulbs in it, checked the fuse which is fine, and the connection. Wondering if there could be something wrong with the wiring.

Hello, I am Danny,

You might want to check the wiring harness (bulb socket) ground wire. Check to see if burnt/corroded/loose connection. I have attached a tutorial for you to view and a picture of the wiring diagram. Hope this helps and thanks for using 2CarPros.
