SATURN SL2 HEATER PROBLEM

2002 Saturn SL2 • 205,000 miles

Hello! I started having problems with my heat this fall. The nicer the days were, the heat would work somewhat, but the colder the days are, brrrr! I had the thermostat replaced which didn't seem to fix the problem. My car is in desperate need of an oil change which is getting done right now. My fan is blowing, but no heat or defrost! Help!

The first I would check is the heater hoses going into the heater core at the fire. Wall. When the engine is at normal operating temp see if both heater hoses are so hot you cant hold them.I bet you have a restricted heater core. Have you ever used stop leak in the cooling system?
