Why is the heat not working on your 5.3L 1999 silverrado Pickup 4x4?
Sounds like your blend door may be broken. the blend door opens and closes on the heater core to allow heat into the cab by letting the air blow over the heater core. The heater core basically looks like a small radiator and when the blend door gets opened up, it allows to air from the blower motor to blow through the heater core fins and that heats the air before it is pushed out the vents into the cab... Check out www.heatertreater.net Those guys have videos on there of what I am talking about. It may not be your blend door though. Could also be the blend door motor or the dial to turn from cold to hot... I would check that blend door first though...
