good thing to mention Neil.
One van I worked on had intermittent temp gauge operation ..
turned out to be very loose temp gauge mounting screws in the circuit.

though with two similar gauges not working, one looks for something
electrical in common to them both usually.
we're waiting to hear the fix !
