My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

What can cause this type of fault here is a short in the interior light wiring keeping the lights on needing traced from each light to see if a short is found or a fault with the BCM (body control module) as this control module controls the lights and can cause this issue here.The BCM is a common component that can short out internally needing replaced.

This will have to be tested further to see if this is the BCM,shorted wiring or possibly the dimmer switch shorted needing replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,a rating of 4 or 5 is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
