I have a 2001 Dodge Durango 4.7 L 4x4 and the vent control will not switch to blow on the floor. Any suggestions? Thanks

I think he means the front.
There's a door in the airbox that switches air between defrost and floor (I assume defrost works, right?). Either that door is jammed or the motor that moves it is burned out.
If defrost doesn't work, then it's the door that selects between panel and floor/defrost that is jammed or has a bad motor.

I had the same issue but my fix was easy. I pulled the control from the dash and reseated all the vacuum lines. Apparently the lines were leaking at the control and not pulling enough vacuum to move the door. I would suggest trying that first since it should only take 10 minutes to do.
Yeah you have a 01 then all servo/actuator driven, I no kidding just got mine put back together today it was a cam unit that failed a extruded piece from the housing (a nipple) that this swivel connects to broke off wouldn't allow the transfer of air flow selection to happen.
This is connected to the large wheel the controls all the movement of the of the defroster rod which extends up from the wheel and the short cam piece that controls floor to vent. This is the piece that was causing me problems the can unit was fine just the nipple on the housing broke I fixed by using a longer screw that went all the way into the housing.
I thought it was a "blend mode door issue" so I tore my entire dash down all of it, I find out I didn't need to lol uggg. I can post some pics of the broken piece to replace would have been the lower housing pretty expensive.
I redid both blend doors in the rear as well both were broke and I purchased a new housing for the rear which I still have as i just used a couple parts off it so I have to fully working actuators/servos if anyone needs a part and a entire rear housing.
The servos are common all the same front and rear.

Awesome, thank you man! So Did you just swing the dash back enough to remove the HVAC unit or completely remove the dash from the vehicle?
Did you find most of the replacement parts at the dealer or online?
Thanks again for the photos!!

Well I know this is old, but does anyone have a specific part number for the defrost door linkage?
My defroster always blows when my heat or a/c is on, so I think the linkage is broken (based on reading from others).

This is for AlphaDog. Thanks a lot...as I'm ready to tear my 02 down...but don't want to. I'm almost positive that my problems are on the left end above the gas pedal as you have indicated with your little screw driver. I don't know where to begin...take out seat? remove steering wheel? etc...can you contact me at 7 0 6 8 2 5 7 1 8 0 my ph? Tks Or e-mail me at gandl2123@gmail.com? Tks Mr. Tripp

Ironic that after reading this a few days ago my blower started only working on high. I had to install a new "blower motor control module" which I got at rockauto for like $3.50.
I guess I need to tear into my dash now to see why my defrost door is stuck open. I still cant find the arm online, anyone have the part number for it?
