1999 Saturn SL1 Heater

So the inside fan works but no heat huh?Well theres a couple of things u can check u can start with checking on the drivers side look in front of the console behind the temp control move it from cold to hot then back the little arm should move with the cable it has a white color sheath on the cable if it doesnt move when ur moving the temp control u need to fix that before u further diagnoses. Next how high does ur temp gauge go up during normal operation?Ok let ur car idle for over thirty mins see if ur upper and lower radiator hoses are both hot becareful not to burn urself also see if ur heater hoses are getting hot too. Let me know what u find.
