Does anyone know how to replace the actuator for a 05 vibe? There is a knocking noise from behind the glove box and i know this is what needs to be done.

I'm having the same problem. Does anyone have a suggestion. I've been told it could be an electrical short, or a bad blower.I just found another thread on the site. Try this; it might help.http://forums.genvibe.com/zerothread?id=35535
