Just a little duct tape and you'll last another ten years!!!
Seriously, that started to happen with my F-250. Things just wouldn't work anymore. Probably the most annoying was the tailgate. I had to take it apart and use a pair of pliers to pull the metal rod inside the door. The plastic parts just wouldn't work anymore and the replacements only lasted for a few months at a time. The list goes on and on, and finally I decided it was worth it to have a monthly payment again. I hate making that payment, but love the truck and how much nicer life is with it.
Good luck,
Eddie
