What to check to fix headlight out due to moisture

I have the original 2021 headlights in and they had accumulated a lot of moisture inside them before I realized it was a problem. I have since fixed that by pulling out the plugs and letting them dry out. The passenger headlight, the long tube light that goes around the outside of the interior is out. Driver is working. What can I check or what can I get to to try to fix this? How do I know if its burned out or the moisture has caused some wiring issue? I don't know anything about these types of bulbs my last truck was an 07. TIA

 

Sounds like it might be worth your while to take some pics & have your dealership handle it as a warranty issue. Even if they say "problem.....what problem?", it might be good to get it "on the record" via a service warranty visit.

 

Yeah. Let the dealer deal w it. Or check DRL fuse.

 

Just make sure it is sealed well. Sometimes new bulbs can be a culprit if they're improperly installed. I see a lot of GMs where the lens is coming off of the housing and allows moisture in without anything immediately obvious. My old truck has this issue mainly with the tail lights. It would cause the contacts in the bulbs to corrode and eventually cause failure.

I agree with going with the dealership though. Especially on something so new.

 

Well, you all make sense. Unfortunately, we are leaving for a 2 week vacation on tuesday. really would like it to work for me on vacation.
