i took my diffusers out a few days ago and resealed my headlights with silicon
but it seems like it was leaking somewhere because i took my car to a car wash
and after i was done, my headlights were gettin foggy.... so what could i do to fix this?

 

I believe there is a service bulletin regarding this. did you try a search?

 

OK, looked around a bit. Here are two threads that address this problem. Looks like it wasn't a service bulletin but you could get it repaired under warranty:

They won't warranty his workmanship.

 

There's only one thing you can do....reseal the headlights!

 

Pull the headlights back out. disassemble the headlight. Reseal. When I did it, I actually scrapped all the old silicone out and replaced it with new silicone. I've had it done since October and haven't had a problem all winter.

 

Maybe play stupid at the dealer...
