Heater problem
2001 Audi A4 4 cyl Two Wheel Drive Automatic 113000 miles

I have a 2001 Audi A4 that the heater is not working. I've adjusted the temperature up/down and I can hear solenoid/valve/door moving. That tells me that the electronic temp. Controller is probably working. Do I have a bad heater core or is there something else wrong?

IS THE RADIATOR FULL OF COOLANT?
ARE THE HEATER HOSES GOING TO THE HEATER CORE HOT AT THE FIREWALL?
IF THEY ARE NOT THEN THE THERMOSTAT IS STUCK OPEN. IF THE INLET HOSE IS HOT AND THE OUTLET HOSE IS COLD OR LUKE WARM, THEN THE HEAER CORE IS STOPPED UP.
HOPE THIS HELPS.
