If the coolant system is full, the heater should still work. However, if the head gasket leak is really bad, it will be impossible to keep full, plus the exhaust bubbling through the coolant could airlock the heater core circulation. The engine is pretty much ruined if its been driven with this kind of problem for more than a couple days - it isn't cooled right and the water in the oil wrecks lubrication. This is a pretty general question - hard to answer - but have someone check it out.

Will a broken head gasket cause heat not to work?

How does blown head gasket happen?
The most common cause of a blown head gasket is an over heating engine. Low coolant or coolant not circulating through the engine causes the engine to heat up and the gasket to fail.
What is the difference between a cracked block and a blown head gasket?
A cracked block means that the engine itself is cracked. A blown head-gasket means that the gasket between the engine and the head has blown. Either can be caused by overheating the engine. When an engine overheats the head can warp causing the head-gasket to give out. In some engines the heat cracks the block. If the block is cracked, it's over. If the head-gasket is blown you can always machine the head surface and put it all back together.
Can a blown head gasket cause a car to overheat?
Yes it can if the coolant has mixed with the oil in the engine from the head gasket being damaged then it will starve the engine of cooling material to flow around the cylinders and will over heat and damage the engine more usually than just a head gasket
What causes the car to over heat and fluids come out the overflow tank?

What causes a gasket to blow?
Defective gasket, poor installation, warped head, heat. Heat is the major cause.
Will a blown head gasket cause your jeep Cherokee to over heat?
Yes. If the head gasket is blown between the water jacket passages and the cylinder it self you are pushing exhaust gases into the water when under load and also possibly leaking a little water back into the cylinder when after you have run it and then shut it off.
Will a cracked head gasket on a 1996 Subaru Legacy L 2.2L cause the car to overheat and the heater to blow out cold air also?
the blown head gasket would make it over heat. but it wouldn't cause the heater to blow cold, it should actually blow hot if that is wat happened
What can cause the motor to over heat on a 2000 Mazda mpv?
Thermostat stuck closed, low of coolant, water pump failure, cooling fan failure, or blown head gasket.
You replaced the thermostat and radiator what else will make it over heat?
Air trapped in the system, defective water pump, blown head gasket or cracked head, cooling fan not working properly.Air trapped in the system, defective water pump, blown head gasket or cracked head, cooling fan not working properly.
What happens if you have a faulty head gasket?
A faulty head gasket will cause power loss, coolant to mix with oil, and is a costly repair. Excessive heat is the primary cause for their failure.
