Hi everyone I have an 04 Limited Durango Hemi. The front blows ice cold and the rear blows warm. Is everything together, or is there a separate system for the rear? Thanks

 

There is a separate blower motor for the rear if you have the rear seat temp controls, however, there is not a separate A/C system.

Sounds like you have some blend doors not functioning properly.

 

Yes there is separate controls for the rear. What are the blend doors?

 

I agree with the blend door. My work truck (not a Dodge) needed the passenger side replaced for $800.00.

So is it a job a mechanically inclined guy could do himself?

 

Well, with the right tools, everything is a job a mechanically inclined guy can do. Most of the jobs I cannot (or do not) do only have to do with the fact that I do not have the proper tools or the time to replace it.

While I do not have any enlightened insight into this particular problem for a Dodge, I had a similar issue with the Olds van that I actually traded for my Dodge.

I had some vents that would blow hot and some blow "cool". After lots of diagnosing, I came to the conclusion that it was my actuator (or blend door). Only problem was that it would have required me to remove the entire dash. Something I could have done, but didn't have the time to do.

Early on, someone had suggested something as simple as low refrigerant. I do not have the nice testing kit one should use, but did attempt to use one of the blue r134a cans that had the gauge on it. At that time, it said the pressure was all good so I ruled that out.

Then winter came and I didn't worry about it too much. However, when it started getting hot again, I went back at it and realized that if everything was off in the car and I wasn't driving (so it was quiet), I would turn the dial from hot to cold and could hear the actuator moving. Just for fun, I bought one of the newer black cans of refrigerant with the more decent looking gauge on it that you can actually adjust for ambient temp (which is important).

Hooked it up and guess what? It was low! It took 1 full and 1 half can of refrigerant and the problem was fixed! That thing blew so cold that I almost didn't want to get rid of it anymore.

Moral: never discount the simplest solution and check it twice! Perhaps that could be your issue as well. Have you either checked it yourself or had it checked?

Thanks Mike! Ill start off by checking/filling the refrigerant then go from there.

 

No problem, just be sure to get the better brand (it is in a black can, not sure what the brand is) and not the white can with the blue gauge. It is a slight risk as this stuff costs like $30-$40 but if that is it, then you are golden. If not, well - perhaps you can save it for later use. It is worth a shot anyway.

btw, as a favor to others with the same problem later on - try to report back even if it doesn't fix the issue.

And be sure that you read the directions thoroughly if you have never done this before. Be sure to use the low side (low pressure) port! Otherwise, you are looking at a painful and dangerous situation,

If your pressures are right I would suspect the expansion valve. THis controls flow to both front and rear and I have seen many fail like this. Not a real bad job to do . I prefer to remove right front fender skirt to access .
