The reason it overheats on defrlost is because less heat is being carried away on defrost than is carried away when the cabin is being heated. As a firststep step visually inspect the radiator inside and out. When the engine is cold. If you can't see a problem you need a mechanic.
Why does my car overheat when I turn the heater on?

Why is my car running hot but not overheating?
If you find that you've got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
Does low coolant cause overheating?

Can low oil cause overheating?
It's usually noticed if your coolant is low, but low oil can also cause the engine to overheat. This can occur even if your coolant level is fine. If there is too little oil in the engine, it will continue to heat up because it has no opportunity to cool.
How expensive is it to replace a heater core?
