Ford Expedition window not staying in regulator

[vwilcox27]

Hey everyone. I have a 1999 Ford Expedition. The driver's side window came off the regulator, so I replaced that and the motor (just because I was in there anyway). Now no matter what I do, the window does not stay in the little black brackets that the glass sits on. I've tried using adhesive with no luck. Any ideas what I'm doing wrong? Thanks for any help in advance.

I have a 2001 with the same issue. Maybe someone can help.

Clean the window with brake cleaner and also window mount. Remove any old glue first. I used blue silicone and put window up for at least 2 days. Also squeeze the mount in alittle.It has held on mine for over 5 years. The glass pulled from the mount when the window was frozen to tracks after ice storm.

There is a special epoxy Ford and glass suppliers market to glue the glass to the regulator. Mine came loose when I tried to open the window when frozen with ice. The epoxy works great.
