Try puling yoru hvac fuse first to see if it will reset actuators, if not lmake sure heat is going to both hoses for heater as well as coolant level being full. Then check to make sure blend door on heater is working all the time. It could be a partially plugged heater core as well but these checks should let you know wha tis going on. Make sure coolant level is full though
