Any update on fixing this issue, mines doing the same thing now, just had the truck at the dealer to do body work after someone hit me and the next day after I picked it up it was dim. One day it brightened up but now it's still dim.
Got side swiped on the driver side and pushed in the fender above the rear wheel, have a small dent on my cab right before the bed. How difficult is it to work on these aluminum bodies, the guy that hit me had AAA insurance and they can't find any body shops here in the area of So Cal that does...
