speedometer not working on my 2001 isuzu rodeo

Take a 12 volt test light and TEST each and every fuse you can find on the vehicle - key needs to be on for testing - this test takes less than 10 minutes and will most likely resolve your problem. IF unfamiliar with how to do this test - seek qualified hands-on help.

Checked all the fuses they are all good still no speedometer what else can I do to fix the problem
