I have this going on from time-to-time with my left front headlight. Also a 2014, factory projectors with halogen bulbs.
I asked my dealer to check it and replace if necessary. It's not bad enough to change the light output but I was concerned about rust or corrosion over time, degrading the lamp.
Instead the dealer told me to use the headlights on every drive, day and night, and it would eventually dry out. I might have thought they would have replaced the unit and take the profit.
I ran the headlights as suggested and it eventually dried out. Since then it has fogged up two more times, then dried out again.
I haven't noticed the tails but will look now. My truck came with the factory LED turns and tails so I don't see the benefit of leaving them on to dry out. On my units I can at least remove the whole rear lamp assembly and I can still remove the reverse bulb to access that chamber.
It is easy enough to remove it from the truck. Might want to try that, see what kind of access you have from all sides. Worst case scenario, prior to simply waiting it out or replacing it, check your kitchen oven? Ours has a convection option and it is digital so I can set it as low as 120F, hardly enough to cause damage from the kind of heat folks see in Texas and Arizona, but I would hope the oven is accurate and consistent.
Exercise caution. Some of my ideas can be whacky, and like many, this plan is not without risks.
