Ok fellow Dodge Lovers. I have recently had to replace ALL of my AC/Heater Doors as many of them were wore out and no longer functional. So I put them all in and unless I run the heat on recirculated air, it is only "Kind of Warm" instead of "Fires of Hell Hot" that it used to be. Made sure my heater core was bled of all air and made sure all doors moved freely before putting the dash back. So now what? Dealer told me I have to bring it in and have them "Reprogram" my blenddoor motors, since they were unhooked for so long and running worn out doors??? Really???? Will this fix my problem? I have another problem that I am putting in a seperate post. So if you would please check it out as well. Thank you.

 

As you are driving down the road, watch the engine heat. If it goes high then low then high again, irratically, you still have an air bubble in the coolant system.

 

It stays the same. Just once you turn heat to recirculated air, It gets "Fires of Hell" hot.
