windshield leaking heater core or heater core hoses.
It can do far worse, such as destroy your engine block. I wouldn't worry about your heater core, I would worry about your Engine.
A leaking heater core will cause the engine to overheat because the coolant is leaking out.
Your heater is powered by your heater core. Your engine coolant runs through your engine gets hot, runs through the core heats the air, then back out to radiator. You probably need to replace your heater core.
low coolant? Bad thermostat? Climate control not sensing proper temperature? Heater core plugged or restricted? Heater core airbound?
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
No it wont. The heater core is just a small radiator inside the cabin that when the fan is turned on heats the air. A bad heater core will cause you to have no heat inside or will leak coolant on the carpet.
you would have to bypass the heater core first.
At the heater core itself.
no.....the heater would have to be leaking
Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
Your heater relay switch may be bad
