I have a 2002 dodge durango the heater in the front is working just fine. The heater for the rear is just blowing out cold air. Any suggestions on what it could be? Thank you.

 

Rear heater core, clogged up somewhere or both...

 

Yeah this is another issue I have, but since summer is almost here, I don't see it as a dire emergency, but on the same note, I don't want to forget about it and not have it when winter hits again... sooooo, where would you locate the rear heater core and if it is clogged... how would you figure that out exactly? So far, everything that I have done to this thing that LOOKED simple... really wasn't! Dodge does NOT make things easy OR CHEAP! Blah!

 

I don't have rear heat on mine (didn't come in our trucks till 2001) so i am not totally sure on locations and stuff but, i would download the 2002 Factory Service Manual here ~~> http://www.mediafire.com/?2cg2hgim2zz

In there look at the heating and air conditioning section and that should give you all the details to where its at and how to replace it.. Get the truck warmed up and turn the rear heat on, then feel the hoses that go into the rear core. If one is hot and the other is cold then you know the core is blocked. If both are cold then you know there is a blockage somewhere between the front and the rear.
