No Cabin Heat?

[RAZRS EDGE]

Hey guys,

2012 F-350 Lariat with 140k miles.

Has anyone had an issue where these things will not blow hot air into the cab? All climate controls work as should except when you crank up the heat, it only blows ambient air. All vents work, all levels of air speed work, A/C blows ice cold, etc. Just no heat. It's dual climate zone and it does not get heat from either side. And yes, coolant level is normal.

Blend door?
The blend door actuator itself?
Do any vacuum lines run to it?

Thank you!

Blend door actuator I am guessing, had the same issue in my 6.4. You can hook up to it and monitor the blend door movement I believe and see if one is stuck.
