Can a bad blower motor indicate a bad heater core?

It may indicate that your blower motor or another component of your heater has gone bad (cheer up, it may be a component that’s less tedious to fix than the heater core). Though, if you’re seeing one of the other signs in addition to a lack of heat that’s a pretty good indicator that the heater core itself has a problem.

What happens when a heater core goes bad?

A heater core often goes bad due to leaking. As the heater core uses engine coolant to generate heat, a leaking heater core will reduce the amount of coolant in the cooling system. Low coolant will cause an engine to run at a higher temperature, which can result in extensive engine damage. Can a Bad Heater Core Cause Overheating?
