Rev counter stopped followed by speedometer this week. Oil, Temp, Gas seem to be ok for the time being. How do I know it is the cluster at fault and not the wiring...dont want shell out money until I know. Can I drive around without a cluster whilst being fixed (is it fixable anyway...or do I need to invest in a new cluster)

The instrument cluster is a hybrid electronic cluster (HEC) with two basic configurations, the base cluster and the optional instrument cluster. In addition to the two basic configurations, the SVT uses a modified optional cluster in combination with a separate oil pressure and oil temperature cluster. The base instrument cluster, optional instrument cluster and the oil pressure and oil temperature cluster receive and output information utilizing both hardwired circuitry and the standard corporate protocol (SCP) or the controller area network (CAN) communication network (2.3L only).
It is very important to understand:
where the input originates from.
all the information necessary in order for a feature to operate.
which module(s) receive(s) the input or command message.
does the module which received the input control the output of the feature, or does it output a message over the SCP or CAN network to another module?
which module controls the output of the feature. Its more then likely you need a new instrument cluster.
I have a Mercedes S-500 and the Cluster Light on my dashboard went out? As you can Imagine I could not see my Speedometer or Rev counter or anything at all. I had no option but to take it to the Mercedes garage In Edinburgh where the fitted a new Cluster Panel complete. It seems now to work fine however at a costly price. Yours Sincerely and thank you very much for your concern and reply. Omzzig.
Chevy is known for using a cheap grade of wiring harnesses that corrode over time and short out. my 93 s10 blazer had a bad wire in the transmission harness resulting in only 2nd and 3rd gear and wouldnt shift by itself, i dont know if im right but something to check into.
