It's nothing to do with the heating system; it'll be either bad earths between the instrument cluster and the motor blowers, the brass nut on the back of the instrument cluster, or a failing heater blower resistor pack:

So have you checked the brass nut, or the earthing point, or the condition of the resistor pack?

Jumping gauge is the brass nut.
Fan stopping is the thermal overload in the fan speed resistor tripping out, probably the fan motor bearings are desperate for their first taste of lubricant in well over twenty years.
