yea if it's the vehicle speed sensor there are a number of things that go out along with it. The ABS light will come on, the brake light will come on. Speedo doesn't work and cruise won't work.
Try The Abs/speed Sensor On The Top Of The Rear Diff. My Buddy Bought A 99 Dually About A Year Ago No Lights On Dash No Speedo And No Cruise This Fixed The Problem Got It At Napa I Think.
mine stopped on the way home, also i know the previous owner so i know they didn't unplug it.
i will check it out today, i'm going to swap the one out of my 95 into it.
Yep, thats how my '95 was. When I replaced mine, I also didn't know that you had the clock the speed sensor the right way or else it wouldn't work. Dumb me! I almost went and got a new one cuz I thought it was bad.
does the tac work? I know it sounds stupid but did you check fuses? I have a truck that needed 02 sensors and had the cel on, when i unplugged the fuse to kill the light the speedo and tac quit aswell. Just a thought, but that was a toyota.
