Heater started blowing cold only since yesterday. Coolant temp. Gauge indicates temp. Just a tad below mid level. Coolant level is OK. Fan seems not to work at the time I started the car and checked after 15 mins of idling.I do not know if that is the way it is or not.
The hoses to the heater control valve get warm after a while but not hot to the touch maybe since it is 15-20 degrees F now. But starting just before reaching the heater control valve the hose gets cold.
All of a sudden I lost heat on my car, it blows cold only even after driving an hour.
What might the problem be and how to solve it?
