Hi! For the past few days I've noticed that after my car has warmed up and is blowing warm air, it will all of a sudden start blowing cold air. This will usually happen after driving the car for about 15-20 minutes.

First, make sure the coolant is full. If it is, check this for me. With the engine warm and the heater on high, check to see if both heater core hoses are hot. Do this when it is blowing cold air and let me know what you find.
