Hmm...

Well, I know it's part of the Remote Control Door Lock Module but cannot find codes or wiring information. I would think that if you tried either way to unlock them it would set an internal code that could be read by a good scan tool. If you have a Tech-2, see if that can open the glass. I've about wore out my eyes for the day looking through my stuff to no avail.

could you elaborate a little more? does it open from the outside button?
and what is a "tag applique button"??? is that some fancy term for the switch on the headliner console?
does the rear windshield wiper operate? because the rear glass and wiper arm are "synced" so that if you open the rear glass the wiper wont pop up and smack you in the face.

Tag applique button that pops open the rear window. It will not open it nor will the key fob. I will have to try the rear wiper to see if it still works.
