So I just bought a 92 F150 and the speedometer doesn't work at all. No bouncing nothing, also the odometer is not showing (digital). I would love some help. Also my turn signals have not worked either.

This happened to me when I bought my used '95 like a week later. Turned out it was just a fuse. Speedo and mileage are on same fuse.

If only it was that simple, already checked the fuses.

Yeah I know what you mean but sometimes I overthink stuff and forget the little things

Speedo's on the same fuse as the interior light.
If not that, it could be a bad PSOM (speedo). fairly easy swap. 92 - 96 will fit ; not the whole cluster, just the center speedo / odometer part. 94 - 5 -6 are the better ones; they were upgraded from the early ones.

That's right. Come to think of it, that last 2 times I went to the car wash, something blew my fuse and took out the speedo and interior light. So I never go to the car wash anymore.

So I changed the psom and the speedo is still not working. Could it be a speed sensor? I know there is one on the rear differential. Isn't there one other as well?

One on the tranny. The rear abs RABS and the cruise control are also tied in to that circuit.

So I replaced the VSS on the rear and the speedo still isn't working. I think I found the other sensor but there is nothing plugged into it. I've heard that 92 and up only have one sensor. I tried to post a pic of the one that has nothing plugged in below. The guy who had the truck before me said he had a new transfer case put in so maybe that's why nothing is plugged in? I'm really stumped guys, thanks for all the help.

Check #8 fuse under dash. My truck did same this morning and after a google search another website had me check that fuse and sure enough it was blown.
