Speedometer doesn't work
 

I just bought a 1992 6.2 l diesel. It had transmission and transfer case work done on it and now the speedometer doesn't work.

i bought a 94 k2500 suburban with the 6.5 td and the speedo quit workin and and wouldnt shift out of first so i looked at all the wiring replaced speed sensors like everyone was telling me and when i finally found it was a loose fuse in the panel wasnt blown just loose

what fuse was it?

it was the fuse for the 4x4 it wasnt blown but just wasnt make connection i took a pocket knife bend the metal pieces that the fuse fits in a put the fuse back in and havent had a problem since
