Moisture in tail light 2021 Yukon Denali

[mpthompson84]

Was at one of those self wash car washes using the pressure washer like I have a million times before and noticed some light condensation building up in my driver side tail light. anyone know if this is a common issue and/or normal behavior on the 21+ Yukons and does anyone have any tips on removing the condensation and fixing the issue?

I assume that your truck is no longer under warranty, as a trip to the dealer would be the solution, if you were.

I have seen a few issues with light housing condensation on this Forum, but not many.

To remove the condensation, remove the light housing and remove the lights from the housing. This will provide openings for the condensation to evaporate out from of the inside of the housing. Then, you will need to do a VERY close inspection of the entire housing to look for tiny cracks or separations in the fixture's mold.
