I have a 07 dodge laramie. I've replaced the heater core cause it was leaking. And tested all five motors under dash while it was apart and they all worked and all the doors seemed to be fine. Put it all back together and no heat. Changed the AC/Heat controls (it has dual climate) , and now it may or maynot blow out dash vents and only heat on past. side just cold on driver. Does anyone have any ideas ???

Sounds like you have air in the core.

Park up hill and run the truck without the rad cap on to operating temp. Hopefully it burp for you.

It has heat, just to one side of truck

Do you know witch motor works the selector door?

 

[K9Kodi]

when you get heat on one side, is the bad side cool or cold air, or no air

 

[scampbell]

It's cool air no warmth at all

Bump. Anyone had to have it calibrated?

I'm going Monday to have it calibrated at the dodge dealer. I'll let you know how it turns out.
