sliding glass door condensation?

Question

During the winter I started noticing what looked like water droplets or other signs of moisture inside my sliding glass door (it's a double pane door). I noted that there was a small gap in the trim on the bottom outside of the door, so i thought a bit of water may have gotten in. I decided to wait until summer and hope it would all go away, and then seal up all the holes in the trim on the outside.

It's been in the mid 90's the past few days, and today i noticed that the water drops are getting bigger. How can there still be moisture inside, wouldn't all the hot/cold cycles every day have gotten the moisture out eventually? How can I eliminate this problem?

Any ideas? thanks, Bill

Your double-pane glass panel has lost its seal. Your choices are to live with it, or replace the glass. There is no practical way to field-repair a failed panel. The glass is a sealed sandwich BEFORE the door is assembled around it. That gap you saw is NOT part of the glass seal- it is probably a weep hole in the plastic surround that holds the glass in the aluminum rails, to let condensation and rain infiltration leak out of them. If not a weep hole, then simple shrinkage in cheap plastic after too many days in the sun.

There is no fix other than replacement of the glass.
