Speedo stopped working the other day as well as the odometer. Cruise control hasnt worked for some time now except now the cruise dash light wont even come on. I tested the harness that goes to the VSS, tested the black wire while the key was off and I got 000v on my multimeter, it had continuity, no open loops. Then I put the key in and ignition to ON and tested the YELLOW wire and I got 12.15v, then I tested the ORANGE wire and got 4.90v. I'm guessing that it all looks right, am I wrong? I thought it might have been the speedo itself, so I swapped the dash cluster out with another dash cluster I have, one that had a working speedo last time i checked, and that one didnt work either. I checked all the fuses, they are all good, even replaced the 10amp fuse that controls the dash cluster with a new one in case the old one was faulty, no change, im not getting any CELs either, wtf?....Is it the VSS or the speedo itself?

 

if it was vss the cel would be on i would try a differnt cluster they go bad alot

 

hmmm. well when my vss went bad the CEL didnt come on consistently, it was sporadic and random. so i wouldnt necessarily say the CEL HAD to be on for it to be the vss. id try buying a vss on ebay($15shipped) and replacing it yourself, first.
