My 02 5.9 at idle blows cool not cold, then while I'm driving it, it starts getting warmer, not like hot air but like ambient tempature, anybody got any ideas?

 

2nd Gen Durango section is for 2004-2009 Durangos. I will move ya to the 1st Gen Durango section.

 

Could just be low on freon.

 

Just got over similar problem. Had dealer do an AC diagnosis while I was getting a promo oil change. Found a leak in the evaporator !!

Dealer wanted $1500 to repair. Needed Evaporator, Dryer, Expansion Valve. The flat rate book allowed between 5 and 8 hours. There are a few posts that detail the job---it is NOT a DIY job--the complete dash and steering column need removed !! There is a bunck stuff under hood that needs removed---dryeris under battery, evaporator refrigerant lines connect at firewall so a lor stuff on upper firewall needs removed.

Two Independant shops bid $1200. one independant shop refude the job--LOL


I got really lucky--friends Dad was in town and he was a Dodge AC tech for 15 years. Parts cost from Cold Air Dist here was $235---Discount Auotparts wanted $375 for parts. Freon was most expensive item on parts list !!!

I watched him do the job---it was not pretty. Took the guy from 730AM to 300PM to remove and replace everything--another hour to pull vacuum and make sure no other leaks in lines or rear evaporator. Took another hour to add oil and feon and final test.

I wouldn't touch that job as DIY after watching a pro do it. Jujst hop hard and long. Find a way to buy parts from a commercial AC house that supplies dealers and indpendant shops to save significant $$ and then find an tech that will work on the side is my suggestion. My total cost was $600 !!
