replacing glass only

Hi, The seal on one panel of a three panel sliding door (12 years old) is broken. Can just the insulated glass unit in this panel be replaced? If not then I'll just live with the cool enhanced view that the moisture provides.

btw - shouldn't it be a criminal offense to sell crap windows like these. The moisture began to appear after only seven years.

On most doors you can just replace the glass. Have someone from a local glass company come out. They will measure the thickness of the IG, the size of the glass, and give you an estimate. It shouldn't be that much.
