I have a 98 Sierra C3500 and the defroster door is loose and has dropped. Any threads here to fix it?

With the way that the air box is constructed, you have to rotate the dash down for access. It’s not as bad as it would seem, here’s a link if you want to tackle it.

The damper actuator has a metal connector that is pressed onto the damper arm. You’d need to be able to hold the damper on one end to tap the metal connector back into place.
