Low Coolant Level
The coolant (usually a mixture of water and antifreeze) in your engine doesn’t just work to keep the engine from overheating: It’s also the source of heat supporting the heating system. If there isn’t enough coolant in your system, the heater core will blow cold air into your car.
Will I have heat if I bypass the heater core?
No you will not still have heat. The heater core uses the hot coolant from your engine and radiates it into the cabin to produce the heat you feel from your vents. Also a bad heater core is a common cause for the heat inside of the vehicle not working.

Flushing out the tubes in the heater core will allow the coolant to flow more easily so there will always be warm coolant to heat up the air going into the cabin. This is especially true if it has been a while since you last changed the coolant as all the buildup can eventually end up in the heater core.
What happens if you bypass heater control valve?
