I'll take a picture of the adjustment drum and post it up here in a little while. First I got to eat me some grub.

My flaps move like they should, when they should, it's just that the knob comes out of the dash too far. After finding the adjustment knob, I got it to stay in the dash, but now the passenger side flap doesn't close all the way.

And about this problem, I took a closer look at everything last night, and I believe my cable is stretched a bit. The knob doesn't go all they way into the dash either. So I believe I can fix the entire problem by bending another loop in it like was suggested. I'll find out tomorrow. Tonight I must relax and enjoy some beers.

Alright Newdrecon, here is a pic of the adjuster drum:


(On a side note, does anyone know what the little red electrical connection is on this duct?)

As for the rest of my problem, I got some pics to show what is going on.

This is the knob in the closed or off position, after I adjusted the cable with the drum:



Notice how it is sticking out a bit. If I force it in all the way, the cable itself kinks. The temp knob sticks out because I didn't have it closed all the way. It sits flush with the housing in the second pic below this one.

And this is the passenger side vent flap as it sits with the knob in the off position:



This is the knob pulled out to the heat position:



And the knob pulled all the way out to open all vents:



It's not coming all the way out of the dash anymore.

This is the vent flap in it's open position:



Since the knob sticks out a bit in the off position and kinks if I push it in any further, I figure that means there is room to add another wrap to it. This should make it so it will close all the way, and stay in the dash when I open it all the way. Then I can adjust the drum so that the vent flap closes all the way, and not have any problems with it again.

At least I hope so.

I went out this morning and gave the cable another wrap to the eye, and put it all back together. Everything works correctly now! Thanks for the advice everyone!

It's for the Fan speed.

There are three wire resistors there that control the amount of current going to the Fan motor.

Since they get very hot, they put it in the path of cool air coming into the heating assembly

Looks like you need to adjust that adjustment barrel to close the passenger side flap. It should be sealed off when the button is pushed in fully.
