Heater stopped heating!

[Marcus]

Hello all,
I’m looking for advice.

On my 2007 ST v8, my heater stopped blowing hot air, or any temperature other than cold.
This happened about 6 months ago but fixed itself after a couple of weeks of me turning the dash temp dial back and forth. Then yesterday it lost all heat again.
I’ve searched this site and it sounds like a heater core might be the problem.

Please let me know if anyone has any recommendations.

Thanks.
