hey guys i finally picked up my 91 4.3l jimmy today and realized the speedo does not work could it be a fuse or the sensor or what would your guys idea I need it fixed asap
brake fues reallyCheck the 15A brake fuse....
Check the DRAC to see if it is connected with the harness.
Does your cruise work?
Any VSS codes(DTC #24)?
Looks can be deceiving, example:ya i know that i looked at the wires all the way to the firewall i didnt see anything wrong they where all in the black wire casing stuff i dont have a dvom to test the sensor im gonna see im my grandfather has one but otherwise i donno
Dat is true ja.Replacing the VSS will not fix an open in the circuit if the open is somewhere between the VSS and the DRAC...........
