speedometer cruise control not working
#1

Fuse 18 feeds the speedometer. There is also a POSM module up there with it that takes the speed sensor signal and conditions it, and sends it to everyone else that needs it, which would be the ECM for the transmission, and the cruise.
Look at the last page on the diagram in this link.

1st thing I would do is unplug the wiring from the speed sensor behind the cluster and then try another fuse. If the fuse is ok with the sensor wiring unplugged, I would trace this wiring back along the frame to the rearend. It may be damaged somewhere.
