I disconnected the battery, I only had 15 minutes and it didn't do anything,

 

Don't have a clue to your initial problem, but the Lariat reset is that set of 3 buttons just to the right of the steering column, below the cluster, and usually hidden by the @#$%! steering wheel.

 

OK, well I can't find anything on how to do a gauge sweep on my dash but it seems to be working fine now??
As I drove around today it just kinda got better, now its working like normal.
Do you guys think one if the abs sensors might be going bad? I was told that's how the speedo works.

 

Spoke too soon, now the gauge is just all over the place.

If it comes down to a dash problem, does anyone know what the cost of replacement might be?
