ok it could be quite simple
lets look at wrong size fuse
example 15 and you need a 25 fuse
also if you did any work on vehicle its quite possible that you grounded something out wrong retrace your work and fix accordingly
bad cluster relay is another problem that would cause these problems

SOURCE: Fuse keeps blowing
Greetings..hopefully we can help or at least isolate the issue. You need to know that there was a few recalls with the cruise control system which is involved.. speedo and odometer is possibly in that circuit..but I am sure the ac had a separate fuse and relay...I do not have a book or schematics here. ,,I would disconect the wires to the ac compressor taking that out of the cause... I would also disconnect the cruise control wire to the unit and drive aroud for a day or so to see what happens. This is whats known as isolate and test . It may take some time but it will give you answers to what is the cause and then check that system out with us. At least you will have it narrowed down...ps ..do not forget at when it happens and what type of roadway ( bumpy, soft, wet, snow) as it all plays a part in diagnostics. I hope this helped.

Check the wire harnesses on top of the transmission for any signs of open plastic casing. You may of had a mouse or some other critter chew their way through some wire insulation which is causing a short to ground,,,, or a short to power. If any are found, spice wires back together ( same colour wires ) and try speedo again.

We had the same problem but when we put in a new fuse it smoked. It turned out to be something with the master cylinder and required the changing of a 20 dollar part by the mechanic and problem solved

The harness on the shifting arm to the OD/tow haul switch pinches and gets cut, this blows the instrument panel fuse. Don't know if this will relate to the hard shift. The shifter arm with switch and wire harness will need to be replaced.
