Found out my right front headlamp was silicone sealed. I believe the major problems from headlamp leaking is condensation/blowing bulbs, and water in trunk?
so I am going to check for evidence of water in trunk. I still have 2 weeks to go back to dealer with problems I find, so I want to leak test anyways.
It hasn't rained here in forever. How should I proceed...
I need to protect the electronics in the trunk, how do I do that?
and if I test one thing at a time am I likely to detect and isolate a leak?
I'm thinking start with hose on headlamp, then at gas cap, then spoiler, what else?

Trying to proceed in an orderly fashion. Please redirect if this is covered in previous thread, thanks
