Tried to crank window down and felt a pop..

[Fbks_Cruiser]

Window lowered about 1/8” before I felt the pop and the the handle just spun freely. Window didn’t go down any further. (It was cold and the window seemed hard to lower). If I turn the handle to raise the window it spins a full rotation or so then something engages and the window goes back up that 1/8”. Try to lower and handle just spins.
I can feel some things moving inside the door when turning the crank and since it does go back up a bit I know it is not just the handle spinning on the regulator.

Maybe one of the rollers broke and came out of the track? You guys think I will need to replace the whole regulator? Won’t know for sure until I get into the door, just looking for ideas from someone who knows these doors better than I do.

Btw it is a 1972.

Take the door panel off and inspect, All parts are available.

If the handle spins freely and then re-engages in the opposite direction you're more than likely going to need to replace the regulator. The regulator in your 72 has a longer shaft than the 69-71 units.

Yeah, that’s what I figured. I’ll have to bring it inside the garage and pull the panel. Wish I didn’t have to remove the vent window to replace the regulator. But then again, don’t need to roll the window down till spring!😁

Thanks for the link to the video. Doesn’t look like too bad of a job.

Pro-tip: I am not a pro at all but I fought with regulators for 10 or so hours before realizing I had to enlarge the hole in the arm that the "wheel" on the regulator goes into. The wheel was bigger than OEM and it was never going to fit until I slightly enlarged the hole. I explained this like crap but you will see what I am talking about.

Thanks for the offer but it is the driver side that failed.

Found the problem. Glass came out of the channel. Guess it was frozen into the weatherstrip. When I tried to crank it down I must have popped the channel off of the glass.

What is the recommended adhesive?

[Astro-Balls]

Cant really see the glass, Did it come out of the U channel that had the rubber packing?
If you can push it back in, use some urethane glue to adhere it.

[Fbks_Cruiser]

Yup. Came out of the U channel. Yes the packing is still in the channel. I just finished cleaning it up. Please look at these photos. Is the channel supposed to bend at the forward edge? Seems to bend down and in? I think it is not right since I can see rub marks at the bend. Also, I don’t think it will fit on the glass like that.

Also when putting the glass back in the U channel does it center fore and aft? Or is there a specific distance from the front or back edge of the glass that the channel is supposed to be?

Thanks .

Did anyone ever give you the distance of where the glass was supposed to be set back into the channel? I am struggling with the same thing. Help please
