NO! THE HEATER CORE IS YOUR CARS HEAT SOURCE YOU CAN BYPASS BUT IS NOT A GOOD IDEAL IN WINTER!

Before CHanging the Heater Core, have you tried flushing it? I have a 99' Jimmy and have to do this every year to get my heater to work.

Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
AC and heater are 2 different systems. The heater works by channeling fluid from your radiator to a heater core usually located under your dash. Heater may not work due to blockage in the line from the radiator or the heater core under your dash may be faulty.
