99 Grand Marquis (crown Vic): Fog / Condenstation INSIDE Headlight Lens

[LieutenantCracker]

About two weeks ago, after driving in steady-rain, I noticed that my right-side headlight had accumulated a small-to-fair ammount of condensate, on the inside of the plastic lens. This has never been a problem before but, I hadn't driven in the rain in 2-3 months so, the CAUSE of the problem could've been there for 3 or more months, & I'm just-now finding-out about it.
TROUBLESHOOTING: My first thought lies w/ the rubber, angled vent-spouts that come out of the back of the headlight housing-- clogged, out of alignment, missing, etc. HOWEVER, I'm not real familiar w/ THAT part o' the car & don't want to go haphazardly poppin' tabs & unscrewin' stuff, and possibly throwing something out of alignment, etc..... Any thoughts about whether or not I'm on the right track?

Since the time of my original posting, I've learneded how to read, and found that I had been overanalyzing/misreading what was otherwise an extremely simple diagram, in my FSM.
CONCLUSION: Rubber elbow-vent on back of housing was clogged w/ dirt (from some form of vermin, no-doubt!)
