I have always had problems with my power locks not working from the key fob but they will work from inside the truck, or vise versa. And sometimes they dont work at all, and I can start my truck and shut it off and it works fine. The problem has generally gotten worse as time went on and the other day, i went to roll down the rear passenger window and it wouldnt go down. but today, it works. Any suggestions on what the problem might be. Its a 04 s-crew Fx4. It also has a remote start that I am guessing might be the problem. But it was installed by the previous owner.
