I did a quick search and couldn't find any similar posts - although, I can remember '00 users discussing this several years ago - so I'll post a new thread.
My center brake light burned out recently, and when I went to change the bulb, I found that the silver plastic housing (beneath the lens) had been melted and bubbled pretty badly :cry: . Also, the gray plastick sockets were discolored, and slightly deformed. The lens showed no signs of heat stress.
I called the dealer to ask if they knew of any heat/melting issues. They said no. I also checked alldata.com, and found not recalls or tsb's on the center light.
Has anyone found this kind of damage on their truck? Since the cargo and brake bulbs are the same, I temporarily swapped them - until I have a chance to buy a new one from Autozone. I guess it'd be nice to get an LED replacement like those for the back brakes.
