Heater problem
1999 Saturn SL2 4 cyl Front Wheel Drive Automatic 103+ miles

The blower is working, but I only get cold air. Is it a thermostat?The passenger floor board is not wet so it is not the heater core. What could I check for?

The first thing I would do is go on the driverside and look and see if the temperture door arm moves with the temp slider control. If thats good make sure both upper and lower hoses are getting hot when the car is at normal operating temp. Does the temp gauge go up to atleast half way when it warms up and u have no heat?Let me know.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
