Have a 2001 Durango and the rear heat takes a very long time to get warm and barely at that. It is not suppose to be that way is it? The heater hose at the back/under of the durango is hot. So do ineed to flush the rear heater core? If so how do i do that i have seen the front done so i know i can do it myself. thanks

 

I'm not too familiar with where the hoses are on the 01-03, but you should be able to pull the hoses for it and stick a garden hose in one until it runs out the other.

 

I plan on doing the core in my 01 but will be cutting it out can smell coolant cant see any dripping, hoses are hot, heater out put okay to start then blows cold oh and my speed relay is burnt out so high fan only
