Not too long ago I noticed the heater in my 159 gasser PM wasn't working. Looking briefly online led me to check the coolant which in fact was just below the low mark. I topped it off with the proper coolant but the heater still doesn't work. To clarify - the blower motor works just fine as does the blend door actuators to go between defrost/front vents/ lower vents. I turn the dial to heat but even with the engine hot it just blows out ambient temperature air.
I'm guessing an airlock somewhere in the system but if that's the case, I'm not sure how to bleed it. Any thoughts?
