Hi there,
I just opened one of my headlights the other day due to one of the supports being snapped and boy it was probably the most difficult thing I ever did on the car. The factory glue that holds the unit together is almost heat resistant but anyway.. I managed to repair the damage, put it back together, job done.
Meanwhile if I had the bumper off I removed the other headlight which has another issue for some years- it's foggy. From autumn to late spring it's fogging all the time. So I said I should take another look at it.
Reading on the web it looks like the main reason for this is some sort of damage to the headlight, a crack, it not being glued together properly and so on. I have to say that it was opened before some years ago to fix another snapped support on it, but I made sure it was glued back on properly and for a while it was fine.
But at some point it started to fog up so I've tried the silica gel packs trick which kinda worked for a while but after it snapped and all that crumbled inside and made a small mess.
Anyway, yesterday I took another good look at it, I didn't see anything suspicious, I removed all the bulbs, used a hair dryer to get the moisture out, also shook it well enough to get rid of that silica gel pebbles. Left it to breathe overnight and this morning I put both headlights back on the car and boom, 15 minutes later the dreaded foggy one fogged up AGAIN.
Now, I want to understand how this fogging phenomenon appears.
They say that if there is a crack(or anything similar) moisture will enter inside and you god fog, but why then every headlight has a vent hole from factory? Isn't that behaving as a crack also?
Btw, I checked the vent hole with the small curved tube attached to be free of any debris and it was fine on both headlights.
On that matter I noticed that there are actually three mountings for that C-rubber that attaches to the vent tube, but only the one where the hose it's attached actually has a slit in it to breathe (see the pics), while the other two are plugged. Why are they there to begin with if they have no purpose?
On the moisture issue the only thing that I can think off is that there is still some moisture trapped inside that I'm unaware of so I just let the car sit nicely underground with one of the bulb rubber covers off to let it breathe.
If that won't work I'm thinking of drilling some small holes into those 2 other vent tubes that are only decorative and see if that helps
Other ideas?
