Heater wont work (how to diagnose and fix)

[dogfish246]

Hey guys,

I dont want anyone to be out in the cold this winter so I made a video on how to diagnose the heating system in our trucks. I go through, step by step, each common problem that causes you to not have heat in your truck (and this can be applied to any vehicle).

Let me know what you think. Also, if your car doesnt have heat and you use this video, let me know what your problem was!

Thanks chrisfix.

I've already replaced my blend door actuator. I'm going to now check my heater core hoses to see if they are clogged.
