    Took drill with 1/16 bit and drilled tiny hole at bottom, lowest point of the fixture. I can hardly see the hole. But a small trickle formed. Should B empty in a few hours.

    Re: Water in the Headlights

    I have had experieince with this problem with a simple correction (solution). Do not drill any additional holes into the housing. This is a common problem with these headlamp assemblies. They leak from the seal around the perimeter of the housing. If and when you can remove the assemblies from the car, just run a bead of silicone around the seal that mates the black rear part of the assembly to the clear plastic that is your lens. I replaced the halogens for HIDs and while I had everything out, I did this. In addition, I replaced the other two bulbs, replaced the access panels and siliconed them to the assembly in case they decided to leak. Everything is now sealed and working perfectly. I don't believe I will have to revisit this with the HIDs installed. I still get the fine condensation once in a while, but once the temperature changes this quickly goes away - this is normal. Good luck!

    There are quite a few threads offering tips and tricks for handling the bumper facia. The dealer will charge you the book number for labor hours.

    And the fact is, they may not even take it completely off. I watched my mechanic replace the headlight assembly with out removing the tire or the entire bumper fascia. It was tight but he got it done.

    Re: Water in the Headlights

    I'd rather do it (or have it done) by the book. What if they damage my car and I don't notice?

    Re: Water in the Headlights

    I can get my fascia off without removing either wheel in about 15 minutes. I dont remove the headlight washers so it isn't completely off the car but enough to access the headlamp assemblies.

    I agree, but my point was if you can't stand there and watch them, how will you ever know if they took it off or not?

    I find that although the dealer said that all was sealed appropriately, I get heavy condensation following running the car through Mike's Drive-Thru Car Wash.

    Again, Because,,, the seal has failed between the body and the lens (as it has for Many of us before) and is easily cured by removing the headlight and running a bead of silicone around that seal.

    (or just keep "moaning" about it if you'd rather.....)

    LOL! I'm moaning because the tech at the dealer who had the facia off looking at it with me said the effort was futile. He refused to do it for me (I have no tools). Said it would prevent any tech from getting inside again. I let him read these posts. I wanted to be sure I was asking him to do the right thing.

    And I don't see how the drive thrus can cause that. But now I continue to moan. But not on this forum.
