Q: Heater not working

asked by on

The heater is out. I smell coolant and steam is coming out of the defrost vents.

If steam is coming out of your vents, the heater core is leaking. Replacement of the heater core on your particular vehicle requires dashboard removal and should only be attempted by qualified technicians like ones from YourMechanic. They will be able to locate any leaks and make the repairs needed to have this issue resolved.
