Can't get any heat????

I'm not able to get any heat inside my car. It blows air through the vents, but won't blow any warm air. Yesterday I had my radiator flushed hoping to get some heat. No such luck. Just wondering if anyone else has had the same problem, or have any ideas what the problem could be? My car is a 1997 SL2. Thanks for your help!

is the car warming up? Operating temperture for your car is a hair above 1/4 on the guage.

Your heater core may need to be taken out and cleaned.
