Its most likely your monovalve. It is the unit that controls the flow of hot coolant into your heater coil. Its like another little radiator that your inside fan blaws across. The mono valve has a diaphragm that often breaks and needs replacing. About $100 if you do it yourself.Performanceproducts.com offers one for $65.
