I have a couple of little things on my truck that Im stuck on if anybody has any advice. First I fixed my passenger side brake light and Its going in and out. It will be working like a champ and then go in and out. Second my speedometer stopped working and I heard that I need a new cable for it. Is this a dealership part or can I get it from a junk yard? And last my dash lights dont come on with my lights. The E-brake light works along with the fuel and seatbelt light but my Backlights dont come on.
