If you got no hot air inside cab and needle rising it would indicate the cooling system is either low in coolant or needs to be bled

Some have a bleed knob on top hose for the heater matrix feed, just outside the bulkhead,

Sometimes its as easy as to start the engine turn the heater on to full heat (not the blower fan) with the header tank cap off and let it run for 2 or 3 mins monitoring the coolant level and topping up as neccessary,

You would need to look on the top of the rad and on the pipes going to the cab heater, also have you a heater in the hab area that is heated off the engine when you are driving?
