Defrost problem
I have a 2003 Ram 1500 4.7L V8. It's a work in progress to say the least. It was bought used from an owner that really didn't know how to take care of a truck, much less keep up regular maintenance or drive it for that matter. Anyways:
So when I turn on the heater, if the **** is turned all the way up to the hottest setting, it never gets warm. It just stays ice cold. I'm thinking it might be the switch, but it could be any number of things causing that.
When the defrost is on, I only get minimal heat or air out of the defrost vents. They eventually do get warmed up and defrost the window, sometimes. Thing is, when the defrost is on, I get strong air out of all of the front vents. I figure that it's the Blend Door, but I'm not 100% sure on that. Any suggestions?

There are videos on the Heater Treater site. Just follow the link I posted and click on the range of years that apply for yourthe Ram in the site. There will be a series of vids posted outlining the repair. I personally haven't done this repair as of yet. Hope that helps!

There are a few youtube video's and written do-it-yourselfer's online.
There is a service manual in the faq section which does step-by-step instructions for remval/installation of the heater elements such as heater core and blend doors.
I would highly suggest replacing the heater core if your tearing things apart!
