   It is an XL 4100 IV model. Single engine unit.

   The single engine models use a hydraulic heater that uses a pump and relief valve to generate heat. It actually does work, but chances are it has never had an oil or filter change in the heater unit, so either the pump is dead or the relief is dead.

   Do you by chance know the location of these two items ? Inside the cab or back near the hydraulics ? Thanks for the info. Ron

   Hydraulic heater unit is behind the cab, look for the small reservoir. The manifold the controls heater and AC is near the main valve
