Q: Heater only blowing cold air.

asked by on

Heater blower works fine, but the heater only blows cold air.

There are two likely causes for your concern. Either your heater core inside your dashboard is clogged, or one of the doors that directs the air to your heater core is malfunctioning. I would enlist the help of a certified mechanic to check your heater for these concerns and have him make the necessary repairs to get your heater blowing hot air again.
