Ok, for those who know how the regulator holds the window glass... theres those 3 clips and the OEM black glue that allows the clips to hold onto the window.

well one of my clips lost grip and I need to reglue it. Question is, what should I use? Window Weld? or some other kind of adhesive... Its a simple fix, just not sure as to what to use. Thanks in advance.

 

I would try the mirror adhesive used to attach rearview mirrors to windshields.
