The inside lights on both tail lights don't light up. The 2 outside lights on both sides work fine. I check the bulbs and they are good, changed them just to make sure. I checked the fuses and didn't find any blown. Any ideas? Thanks.

 

Have you tested for power to those lights specifically?

If stock lighting, the inside lights only function as tail lights....not brake or turn.
