Heat started to stop on passenger side an eventually stopped. Driver side heat started to ge cooler and eventally stopped. I peformed a backfush on the heater core, fushed the whole system and even replaced the thermostat.
Got heat back on driver side but not the greatest. Passenger side is still cool. Before and after the heater flush the inlet and outlet hoses are both basically the same temperature, very warm, but not hot to the touch. The directional control works such as feet, vents, defrost, etc. and there is full working fan control. When I did the flush i noticed white specks/pieces of "scaling" the thermostat was covered with it. Apparently the coolant was never changed on it until now, ten years.
I followed the correct "bleeding" when adding the new coolant at 60/40 ratio. At this point i figure it may be a blend door issue and may action next. I starting to not like working on this vehicle's engine. I thing the engineers were high on something when designing this car. Everything is compact or just weird to work on with.
