2003 newmar freightliner speedometer stopped working

Hello,

I’m looking for some advice. I recently purchased a 2003 Newmar motorhome built on a Freightliner chassis, and all of the gauges are not working.

The previous owner told me they all stopped working on the same day.

I have already replaced the VDC with a brand-new unit, so at this point it seems the issue may be related to the instrument cluster.

Does anyone have experience or knowledge with this type of motorhome?
