ML 320 window attachment to regulator

[sunedog]

Have a 1999 ML 320 and the front passenger side window stopped going down. I determined the switch, motor, and regulator all work, but the window has become detached from the regulator. (I am well aware of the window switch problems and this is not a switch problem.)

I pulled the inner door off and confirmed the motor makes the regulator operate smoothly. Unlike the drawings I have seen of other regulators, mine does not have clips attaching the regulator to the glass. Mine has a channel the glass fits into. I can manually pull the window down and seat it in the channel. But when I put it up and then down, the window stays in the up position.

Can someone tell me how the window is supposed to attach to the regulator? Here is a pic of the regulator in the full down position showing the channel:

Since none of youse guys could help me, I had to look elsewhere for help.

Called my favorite indy (Imports Plus -- Irmo, SC <-- great people) and luckily for me, the Free Advice Counter was open. Service advisor David was pretty sure the glass is bonded to the metal channel with some sort of adhesive. He suggested I go to a glass shop. Great idea!

So I went to Sheperd's Glass in West Columbia, SC (also great people) and a young man examined the innards of my door and concluded a urethane adhesive would do the trick. $12 and some change later, I was on my way with a tube of Dow Betaseal U-418 Quick Cure Primerless Auto Glass Urethane Adhesive.

When I got home, I filled the metal channel as best I could considering the limited accessibility and then firmly seated the glass and put the window all the way up. My glass friend said leave it undisturbed overnight. I waited two full days and it now seems to work perfectly. Put the inner door back on and all is well.
