hello everyone. My Z came with some aftermarket headlights that had a lot of problems so I went ahead and bought brand new Nissan headlights. New ballast, ballast oring, bulbs etc. I took the car to the car wash once and the passenger side only got a lot of foggy condensation inside. A couple days later my new ballast died bc the hid won’t turn on. It’s an 03 btw and yes I have fenderliners. I got pissed and got a hair dryer and took a bulb out to try it but it came back. I called Nissan and they’re shipping a new one to me very soon with a ballast. When I took the headlight out and checked the ballast it was drenched in water which makes me believe the water got in where the ballast screws on to. How do I prevent this? Was it just bad luck that I got a bad headlight? Or what gives? I sealed everything and installed it all correct. Any ideas guys? Also one thing I think caused it is that my fender liner for some reason doesent completely make a seal with the bumper on the passenger side. Wheel. There is a little opening there. Any ideas how to fix? Again thank you all that took the time to read this. Happy New Years guys!

Lol haha. Do you have any idea buddy?

Well that’s good to know because I sealed the headlight and the ballast inside of my warm home so that’s good. I just got the headlight in last night and adjusted it and it looks amazing with no water or vapor inside. I used a little extra bit of silicone just in case. But I hope it doesent happen again I’m avoiding car washes for now on. I think the strong jet of water is what did it
