I’ve been getting some (a lot of) condensation in both my headlights on my gen3.5. It’s not as bad on the driver side as it is on the passenger side. I don’t see any visible cracks on the housing.

Another thing to note is it started happening on the passenger side after my friend pulled out the high beam bulb on that side. I was trying to install the DRL resister kit and he mistakingly pulled out the high beam bulb and didn’t install it correctly.

A week later I went to go wash the car and notice the passenger side headlight fogging up. I checked and saw the high beam bulb was not installed correctly and fixed it. In the process I also pulled the high beam bulb from the drivers side to inspect and also the low beam bulbs form both side. The following day I noticed condensation on both headlights. Now every time it rains or I was the car both headlights fog up, however, it isn’t too bad on the drivers side.

I have tried everything to fix this including taking out all the bulbs on both side, using a hair dryer to get rid of the condensation, and install the bulbs with some dielectric grease around the o-rings. But as you can see it hasn’t helped.

Now my next suspicion is that maybe the rubber boot around the high or low beam bulbs is not seated correctly which may be causing this issue.

If anyone has any suggestions on what I can try it would be appreciated. Thanks.
