Ive been having light issues with my car for about 6mo's now.First it was the passenger low light that I couldn't get to work even after a brand new set of HID bulbs. I bought a new set of headlight housings because I noticed condensation in the casing on the passenger side. I then bought a new ballast for it and things were good.
Soon after my dash lights didn't work and now my back lights don't either. I changed the corresponding fuse inside and they still do not work. As it turns out its been raining as of late and the new headlight housing I just bought also has condensation and light doesn't work again so now Im back to square one...Please help!..Im about to go postal on my car!
