cooling fan problem 2010 6.7

They replaced the fan unit once because it didn't shut off but it still runs . It doesn't matter where the controls are set . On heater only or any other settings. I know it should run when you have it on defost or ac. Anyone else having trouble? Tim

Im going to look at mine this evening as I swear its always on when the key is in. It can be 30 degrees out first start and fan will come on.

What fan are you talking about, the engine cooling fan or the HVAC fan?

I think he meant HVAC fan, not cooling fan(engine).

Are you saying that it is on when you first start the truck? Or when you have the key in the on position with the truck off?

If it's the mechanical / engine driven fan under the hood...it's always going to spin, somewhat. It's friction in the system.

I know the difference if the engine fan is on or not .I operate 7 class 8 trucks. when you open the hood with the truck at a fast idle and it blows your hair back , its on.

That is great I used to own five class 8's myself, but that is irrelevant here. A dodge is not a Peterbilt.

When it comes to trouble shooting you got to start somewhere. That is the reason for the basic Q&A. Sorry if your offended, but I really had a hard time understanding what you asked in your first post.
