Hello, is it true for each door? Or have you checked only the driver's door? That's important, because if a door switch is stuck in the "closed" position, then it's possible this is the culprit. But it would be highly unusual for all door switches to fail at the same time! Secondly, there is likely a lighting module that commands lighting controls. So a diagnostic tool interfacing with this module could be helpful. It's all about "hands on" testing to see what's going on. Seek guidance at a local shop near you should you run into a dead end. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
