W140 S420 main Glovebox stuck!

[wildirishtime]

Dash glovebox stuck in my 96 S420. I press the release button
on the dash and I feel no resistance like I do the sunglasses glovebox
(which IS working), the button feels disconnected from any linkage regardless of the key lock position.

I don't know where to start and I was unable to locate any reference
to anyone else having this problem. It has been stuck ever since
I purchased the car 2 weeks ago, so who knows what I'll find.

THank you for your direction and assistance!
