Hello all, this is my first post in the f-150 section as I drive a 250. I bought a 97 f-150 today that needs a little work. The mileage is 96,365 and I noticed that after driving it back to the job site the mileage hadnt changed at all. The speedometer and all other gauges work. Odo and trip odo are the only ones that dont work. Can anyone point me in the right direction on finding the problem? What can cause this? How easy of a fix will this be? Thanks in advance guys
