No heat issue

[Garrett798]

I have 21 RAM 3500 6.7 with around 95,000 miles on it and i noticed that the driver side heat is much cooler than the passenger side with the heat on high. I have seen many things on blend doors and blend door actuators on older models of this truck but haven't found anything on a 5th gen. If it is just the actuator, can it be changed without pulling the whole dash, and is there a way to identify what the problem actually is?

You might have better luck in the Homepage - HD Rams forum. This is the 5th Gen 1500 Rams site.

It is a heated core. You can back flush with a garden hose to get heat working again.
