Why am I not getting heat in my 1996 Chevy Suburban?

Normally I hear that the floor will get wet when the heater core goes out. Well I don't feel any water any where. Where is the core located and how do I know if it is working or not? Is it in the enclosed casing in the rear? This is a bad time to not have any heat in the ride. And bad enough. It's the wives transportation. Cone on guys. Help me out. When the climate control is turned to heat, nothing but cool air or just air. Not air like the A/C is running. More like fan mode. I tried running it and went to the back to see if the thing in the enclosed compartment was running. Nothing.

Look under your hood,make sure your anti-freeze level is good.Then check your heater control valve on the fire wall,make sure it's opening and closing when you slide the switch to the red zone.
