Resolved Question:

2000 S-10 Blazer 4.3 L V6. My speedometer quit working. I am not getting any trouble codes but I replaced the VSS anyway hoping that it was the problem but it wasn't. My next assumption is that it is the speedometer itself. Is there any way of confirming a faulty speedometer before I buy a new one?

Hello, yes there is a way to check but a diagnostic scan tool or an osciloscope will need to be used to determine if the vss is giving a signal. I will send you the diagnostic procedure just in case you are ablr to use it. I hope this answers your question. If so please click the accept button. Thank you JAY.

Would it be possible to get a copy of the wiring diagram showing the colors of the wires from the VSS to computer and gauge cluster?
