It probably has something to do with the tires. Does it have the original size tires on the truck? If so then maybe someone had changed the speedo gear when they had bigger or smaller size tire on the truck.

You must remove the complete heater core and a/c evaporator from under the dash. It goes from the center of the dash to the passanger side of the dash. You have to remove the glove box, remove the heater hoses, vac. lines to the controlers. Bolts that hold the unit to the firewall. Also must remove small vents at bottom of the dash. Would be much easier if you would just tell me what area you are having problems with. After you are done you will have to recharge your a/c system. This is not a job for a novice.

do the head lights work????????that is first
becaus it works key off a speaks volume to any tech

wild guess:
battery installed backwards or you made sparks
remove it or alt or starter.
fuses blew.
easy peasy japaneezy
or worse,there is always that.?

elaborations. pretending HL work.
buy and $10 voltmeter and end the guessing?
5min work and bingo.
wow this fuse has 12vdc one side and 0 other.?
or key on fuses, same.

there are many ways to do this.
start at end work back
start and begin (key) and work forward
or the middle (cuts job in half too)

so i go to the starter solenoid first.
if head lights dead i work them first....
starter 3 lugs.
outboard lug first.(batter + is battery installed backward?)
got +12v on the big lug (y/n) (outside lug)
connect meter neg test lead to battery neg lug for all tests.
if voltage drops fast? or does cranking
bad battery ,starter shorted or cables (or discharged battery) (we use an ammeter to discover shorted starters,or hand turn engine for seized engines.
next tiny lug, (called Key Line)
it goes hot 12v? cranking. so turn key.
does it go hot? (hot means 10to 12v cranking0
if yes, goes hot cranking on the tiny lug
(yes starter dead , or the battery minus lug is loose , the far end of minus bat cable must be tight.
no? that means the KEY line is dead.
the car if a/t tranny cuts the key line via the P/N switch,or some immobilizers., i stop here on key line, ask.

some cars have wire fuses, looks like wire, and are not. "fusible link wires"
if you change out starter or alt without battery neg lug not disconnected in step 1 ,you risk main fuses under hood(blowing or far worse)
so what does "good fuses mean" OP? (the looks)>?
or just dash fuses. tested skipped under hood.
fuses that look bad are
fuses that look ok, can in fact have hair line cracks so we actually test them or waste Huge time.
and go poor. (tests done wrong are highway-to-h3ll)
or looks like dog chasing his tail.
0 ohms good
12v both sides key on, good.07316db1-a220-4760-a228-0a546c4edbe8.jpg

Leaking of any fluid is not normal. The only time any fluid should expel from the car is if you have overfilled something. Your turbo could need replacing, you could have a hole in the intercooler. Have you noticed any lack of performance or extra smoke...
