It would seem simple to separate the light assembly put it back together and use some type of waterproof sealant and not have to replace the whole light housing. Appreciate any comments that anyone might have. My 98 is the stock 2 door coupe with the 3800 engine.
Bill, I have to ask....why do they need to be cleaned? They should
be sealed up tight where nothing gets in them. If you have condensation that means you have a crack.
If you really want to get them apart, you can do it without tearing them up. Follow these steps and you can do it yourself......
Remove headlights from the car. There is one 10mm bolt behind each headlight. Remove it, push in and slide the light towards the center of the car to remove it from the bracket. Turn the bulbs to remove them from the housing. Remove the four little silver clips holding the lense to the housing.
Heat up your oven to around 300 degrees. Stay by it the whole time when you're doing this step, so you do not accidently melt your headlights. Put in one headlight at a time on a piece of wood (so the metal grate does not melt the plastic). Leave in there for around 10 minutes. When you pull it out, it will be hot. Stick a flathead screwdriver or butterknife in between the housing and the lense and pry it apart. If it does not budge, heat it up more. Be very careful and go slow - the housing is very brittle and will break easily if you pry against it too hard. Once you have the lense seperated from the housing, clean off any old silicon that you can. It doesn't have to be perfect but the less old stuff that is on there, the better it will adhere.
Do your cleaning
Clean the housing with acetone (nail polish remover) or some kind of alcohol. Your fingerprints, old glue, etc must be cleaned off. Admire your work. Now's a good time to polish your lenses if they are hazy. When both parts are clean, you may put them back together. The easiest way to do this is to lay the housing face up on a flat surface. Fill the channel around it lavishly with silicon sealant. Lay the lense on top of it, and press down firmly, holding it like that for a minute or so. Reattach the silver clips and give the silicon enough time to set up!!
Now it's finished and ready for reassembly.
Hope this helps,
