Question about 1999 Chevrolet Silverado 1500
The problem is most likely the control panel. it is very common that they go out and very easy to replace. just pop off the face plate that surrounds your heater controls. then pop out the heater controls. no tools are required. take that to a dealer and get a new one.

Could be the heater core valve, check the cable that opens and closes the water valve to the heater core.
check also the setting of the temperature level. it could still be set to cold.
wait for a few minutes for the water to heat up on the radiator. you could have tested it after you start the car and the engine is still cold.
