Need help with proper procedure to remove drivers side door panel. Ice and snow, knocked my window off of it's track? Motor runs, window popped , and now it won't go down.

Is it as simple as popping roller back into an actuator arm?

Thanks in advance

 

No because you're just guessing that is the cause. The regulator could've broke, or a gear could've stripped just as easily.

 

Do you know how to remove the door panel, so I can observe and hopefully determine what broke?

 

You didn't specify your make and model, but here is a video for 97-03:

 

My fault, 99 Navigator, thanks
