Exhaust brake, and tow haul shut off

[Bob4x4]

The problem with our recirculation doors is that Dodge ignored them until confronted with the warranty repair or confronted by a dissatisfied customer that has complained since day one until finally it totally failed after warranty. Then, and only then, do they tell me, (oops :-laf), tell us , that it needs replacement and want $900. 00 for the repair. The ****** off look on my face told the service writer I was going to go over his head when he talked to upper management, then had offered half cost.

Sounds like a sore subject for you

Clarification

I'm also in the HVAC world and a lic. contractor, and also taught for a couple of years. You couldn't of said it better, but what I do to help my AC catch up to high cabin heat, is to crack the windows open slightly and open the system to outside air, which causes a positive air condition in the cab and pushes out the high heat built up in the cab. Then I select recirculation and keep it there until I get out. I guess you can say this helps in relieving stress on the system, seeing how the outside air is cooler than the cabin air, therefore it helps keep the refrigerant pressures lower. But that isn't why I do it, I do it to cool the cab quicker.



On my 04. 5 CTD I had the issue of the vent door from day one, my wife would always complain of being warmer and when climbing grades we would get the diesel smell from the big rigs. When I complained to the dealer, I was told that they are required to have a little fresh air entering the cab. That was bogus, but I believed it at the time, because of the fresh air requirements on building AC systems. When my vent door failed completely it was out of warranty and they paid for half the cost. Once the vent door was fixed, all the issues my wife complained about went away, to include no more diesel smell on grades.

Yes, I should clarify to eliminate misconceptions, when you first ener your vehicle on a hot day you need to ventilate the cabin to the outside because the outside air is cooler than the inside air, BUT, when they become equal you switch to "Recirc" to keep that cooler air inside and reduce the load on the system and NOT introduce hotter air on to the cooling coil and you can achieve an even cooler cabin temprature by reducing the introduction of the hot outside air thus reducing the load on the system and stress on the engine AND reduce fuel consuption and load not to mention reducing outside pulutants into the cabin. Now if there was only some way to reduce misconceptions in the understanding and the operation and maintainence of HVAC/R equipment but I gueass I ask for to much.
