Does this vehicle use a boost pump? A lot of these I have seen use a boost pump to supply enough coolant to the heater itself.

no boost pump

Bleeding the system must not have helped?

Had to add an inline lift pump to the system to get heat to the rear. Newer ambulances have these so the ambulance company suggested it and it took care it took care of it . Thanks
