Hey guys, I installed a new set of OEM projectors on my 2011 f150 XL. They have been working just fine for about 5 months and here within the last week they won't turn on for anywhere from 2-10 min. So I have to just sit there and wait for em to what I call "warm-up". I'm not sure if it has to do anything with the cold weather or possibly water got somewhere it shouldn't? Anyone else have this problem? Any fixes to it? Thanks
