I have no clue where to go with this one. Even though the truck is barely over two years old I have put 52,000 on it so it is out of warranty and I can't find any manuals for 06's yet. A few months ago the passenger side headlight went out. I flashed the high beams and it went back just fine. I had to do that more and more often until finally the low beam on that side stopped working all together. Then the high beam even went out. So now I have no headlight on the passenger side. I've replaced the bulb, swapped bulbs from one side to the other and nothing helps. All other bulbs in the passenger side assembly are working fine as are all other lights and electrical. I thought maybe the headlight switch or the hi/low switch but either of those would affect both sides, not just the passenger side, right? Any ideas would be appreciated.

Anyone?
