condensation in headlight

hi,
my 99/v astra has some condensation in the headlight i thought i'd
remove it and try and dry it out somehow but looking at the manual it seems
you have to take the bumper off. i don't really want to go to all that
hassle anyone got any ideas?
thanks in advance

Might seem a silly idea mate,
but can't you leave the headlight on for a while, maybe in front of a mirror
?
The heat should dry the h/l out.

 

turning the h/l on might warm it up, but the water (vapour) would not be
able to get out. when it cooled down it would be back to square one.

how about blowing a hairdryer in through the bulb hole? maybe use a funnel
poken in if you have the room, so you actually get an in-out airflow?

Fair point well made!

 

take the buld out, and the upper and lower breather things.
bung a hair dryer into the now vacant hole.
might be an idea to smear some silicone sealant around the lense edges
afterward.
if that's how the water got in.

I had the same on the indicator lens. Easy to pop out if you can get to the
plastic lugs (with a long screwdriver). Sat it on a radiator overnight,
siliconed around the edges, then chucked a couple of silica gel sachets in.
It still had some mist in, so I dried out the sachets on the radiator, and
bunged them in again, then removed them a few days later.

thanks mike worked a treat.

It will probably come back though. It was a common problem with these.

The seal between the lens and the rest of the lamp is probably shot.

The warranty cure was to replace the headlamp and adjust the bonnet
bump stops upwards (unscrew the rubber bung a little) so the bonnet
does not hit the top of the headlamp.

Unfortunately, as has been pointed out, all this has done is fix the
symptom, not the initial problem. (water getting in in the first place).
still, at least you can easily do something, and thanks for letting us know
it worked!
