Hello I will help you with your question,
There are several junctios between the lamps and the underhood fuse block. It could be one of those or the ground for the lamps.
Do you have a 12 volt testlight or voltmeter to check the circuit?
It could be but if you can do some testing you might be able to bypass unnecessary panel removal.
I plan on being here tomorrow so post back when you are ready and we can check the fuse then the lamps for power.
Let me know so I can help
