I bought a replacement cluster for my f150, already programmed to my correct mileage and the key memory was blanked out at the vendor. They said as long as I had a key without an "S", and one or more with an "S", one most likely was a master and the others are slaves...well that is not the case. All 3 of my keys must be slaves as now I have the theft light on.
The original problem is the odometer does not always display but I am told the miles are correct. My dealer wanted $475+ to R&R my cluster and replace it. By doing this on my own, it's about $200 with my own labor. I am also going from an XL to an XLT cluster to get the tach benefit. I wonder if there is a secret warranty on the odometers - isn't displaying mileage a federal requirement?
Can I reinstall the old cluster and start the truck?
The only other choice I have is to have the truck towed to the dealer 1/2 hr away where I bought the truck 2 1/2 years ago. I remember when I picked it up, I had already told them I wanted a 3rd key, and they forgot to program it and tripped the PATS. Somehow they corrected that condition that night, even though service was already closed. Rocky
