Maybe I'm the odd one out.
I've had good luck with rear view mirror adhesive on the vent windows.

Keep in mind that you are attempting to glue two non-porus virtually flat surfaces. That is a challenge for any adhesive.

Both surfaces must be spotless. After you've cleaned them, clean them again. I've wiped them down with mineral spirits followed by brake cleaner followed by alcohol. Let them dry thoroughly.
Follow the directions on the adhesive. It doesn't take a real lot to get good adhesion. Remember, you're not filling any pores with adhesive. That's why you don't need much. My experience is that too much will not hold. Don't clamp it too hard because you'll squeeze all the adhesive out.

Be patient. It will work eventually. It may take you a few tries - I know it did for me.

If you give up, IPD used to sell aftermarket latches that did not need any glue. They would just grasp around the edge of the glass.

Good luck.
