Replaced the fuse,no change.Light on unit under hood lights up when I push button,but does not flash any code.Not even a one.Dash light does not light,wire is dead.Tried my home made tool to check for blinking code ,nada.
Dumb question,do codes come from computer or that box under hood.I do smogs and have seen this problem about 4 times now,so i would think computer is the source of codes.Just does not hurt to ask.
This week i will check IATN for info from them.
Thanks for your time Mr. Dalton
