My heating system has all of a sudden statrted not getting warm all the time especially if I have it on defrost/floor. I had thermostat changed and system flushed. I have kept the car in great mechanical condition, no other problems. Any ideas?
Before removing anything I would also make sure both heater hoses going into the heater core at the firewall are getting too hot to hold when the engine is warmed up?Also watch if the blend door is operating.
