Condensation in headlight

[Deleted]

I just installed a 180 t-stat and adjusted the fan settings by dropping them all 10 degrees (185-188) with my Predator tuner, the install was quick and easy. The next day I notice that my drivers side headlight is full of condensation, I have had my car for almost a year now and have never experienced this issue before so im wondering if the t-stat change is causing this condensation issue. Anyone else have this issue or have any suggestions on how to solve it? I have a 2008 Charger SRT8 with a Procharger installed, your suggestions are appreciated. That condensation might slow me down in the races this friday

What if you took the headlight out and checked the seal? There is probably a leak in it and with the humidity we have had the last few days is causing moisture to get inside. Just my $.2. LOL

Just changing the T-Stat wouldn't cause anything like that. I don't think they are related.

Thanks for the replies. I was kinda hoping it wasnt the seal that was causing the problem because i would have to remove the front bumper (fascia) to remove the housing for the headlight to properly seal it.

From what I hear its pretty easy to take off.

The 2 have nothing to do with each other. Many of us have changed our T stat without any condensation build up in headlight housing. The question that begs to differ, is have you changed your light bulbs recently? do you high pressure wash your car, especially headlights?
does it go away once the headlights are turn on, due to heat drying up the moisture? Good Luck locating source of condensation but I am pretty confident changing T stat and adjusting fan setting have nothing to do with moisture build up.

Condensation in the headlight has nothing to do with the t-stat. I've taken the front fascia off so many times, I can get it done in about 30 minutes. The seal up the light is very simple. Also check the seal around the light bulbs to make sure there aren't any leaks there.

I'm with Chris. Check bulb seals and so on. It takes a lot to break the factory seal on a headlight, especially all of a sudden like that. I've seen this plenty of times on all sorts of cars when I worked at the dealership or body shop. My suggestion is take a close look at the seals/boots around all wiring entering the light housing. Remove and reinstall them a couple times to ensure they are sealed correctly. If they feel dry or worn, try some liquid silicone (even vaseline works) to moisturize them and make them flexible again, but use only a small amount. Really check to make sure the boots are still "locked" on the harness portion where they are supposed to be. These often have a pattern in them somewhere to ensure they sit correctly, the least of distortion at this joint allows moisture to infiltrate. Most everything relies on pressure in the area of bulbs sealing, a little slack, some humidity, or a power wash is all it takes to cause this issue.

the back side close to the high beam there is a rectangle tape behind it 2 good size holes that could cause it
