Two possibilities come to mind. First is that the lever isn't connected to the valve that opens the flow of water to the rear heater. Second is possibly a big air lock in the pipework to the rear heater matrix.

third option is sludge in the pipes from not being used for a dogs age...

theres 2 pipes just below thermostat, take em both off and bung a hose pipe up it (with the heater in the hot position...) and plf. make sure the system is nt airlocked when you put it back together tho. good luck!

The rear heater seams to have very fine cooling fins & as said the pipes get full of brown sandy sludge.
