Can a blend door go out of whack?

[98dieselburb]

Here is the problem guys...

A while back, the one link fell off one of the blend doors...It was the upper one closest to the dash. I reached up in there (very tight fit) and tried to put it back on. I did get it on, but since then, it seems as though I get hardly any floor heat, and minimal defrost. Most all of it seems to want to come out of the dash AC vents... I was wondering if by some chance that i installed it wrong. Anyone have any thoughts?

I have since replaced the actuator motor and the main controller. This is driving me to drink...lol

Thanks!

They mount on a pivot inside the box.

Sometimes they slip out and don't move properly.

Something like this:

If you pull the bottom vent off the center floor heat you can probably look up and see if it it engaged. Probably watch it move (or not move) on selection too.

Might not be your problem, but it's a quick and easy check.

That was my problem a while back. Door looked exactly like that one (Rubber coming off). Had to replace it to make it stay put.
