Hey Man;
Thanks for the information....I did what was indicated and sure enough the door was broken and I removed it...Can you tell me what the purpose of that door is? Will it hurt the vehicle to NOT replace the door?---Buddyruff

I had the exact same problem on my 2001 Dodge Ram with the cummings diesel engine. I checked the blend door motor and it was working fine. After removing the glove box I could feel the heater core and it was quite hot so I knew there was not a circulation issue with the hot water coming from the engine. I concluded that the heater core must be clogged up with debris where the air flowed through it....Sooo I went through the wonderful experience of dropping the steering colum / partially removing the dash / unhooking the heater and a/c lines / removing the heater / a/c unit from the firewall only to pull the heater core out of the unit....And low and behold it was in perfect conditon. No debris in it what so ever. I decided to go ahead and replace it and since I had gone that far I decided to break open the case and replace the evaporator core as well. That is when I discovered the reason for the entire problem. The evaporator core was extremely clogged with debris and was showing signs of oil leaking from it. I am amazed that I had such a good working air conitioner and such stong air flow with the evaporator core clogged so badly. Anyway after replacing the both the heater core and the evaportor core my truck now blows extreamy hot air. I am sure I am not the first one to find this problem but is does sound like it could be what you are up against as well. Please let me know if my situation turns out to be the same as yours.

Buddyruff, at the time I posted the fix, I did not know the purpose of the door. Now I do. It is used to close off outside air mix in order to heat or cool the cab faster. It can also be used to keep the cab cooler in extreme heat like Florida. Since I have removed the door, I have noticed no difference other than the air REALLY blows now! Could be I was just used the anemic air flow when the door was broken and laying over the fan. Thanx for posting. The administrator has informed me that this has been posted before, but it must have been awhile ago. Also, Dodge is supposed to know about it as they have a repair bulletin out. My dealer didn't seem to know the easy fix and wanted $700 to look into it. Benchmark of Birmingham. They should really be just pulling those doors out for people. Stevo

Hey Stevo--Buddyruff here...I did take the recirc door off and air blows out great..Now the problem is it only comes out the vent--hot; cold is fine just out the vents with very little out the floor and none out the defrost..I turn the switch to eacj location and it still just comes out the vent...Is there something else now wrong??? By NOT replacing the recirc. door; did that mess it all up or create a new problem?? As winter is approaching I need to get his fixed...any ideas???
Thanks !!

recirculation door

Buddyruff, I believe there may be some other issue with your truck. The door only controls the recirculation choice. All of the other selections: defrost, floor, etc., should work normally. On the defrost, it doesn't normally blow hard up there, so it may seem like it's not working. By removing the recirc door, you would not effect the other functions of the climate system, only the ability to close off the outside air. Most people who remove it, find the air blows even harder than original. You may be correct about some change to the defrost and floor does happen when the door is off. At least, you have good circ thru the vents now. There may be another door between the defrost and floor. If it is of the same quality as the recirc door, it could break off as well. Hope this helps. Stevo

Sounds like a vacume leak to the control doors. It could be anywhere from under the hood to in the control knob area. That is what I would eliminate before looking for anything else.

Fan Speed Controller-only works on highest setting

I've begun to take apart the dash panels to find the broken blend doors and realize I'd better get this fan speed problem tackled at the same time. For the fan to run, I have to turn the dial completely to the right. There are no intermediate fan speeds in operation. How do I troubleshoot/fix that problem?

The recirculation/fresh air blend door is broken off and is blocking the airflow of your fan. Remove the 3 screws holding the fan on (floor, pass side), reach in to the left and fish door out by moving it around until it can get thru the opening. You don't need this door really, so don't replace it. Stevo
