Window drop sensor issue

[bottman5684]

Hi all,
I searched for previous postings about this issue, but could not find any. Occasionally when I hit a sharp bump, my side windows switch into "the top is opening" mode. I have to pull over and fiddle and fiddle and fiddle with the top until finally the windows decide to roll up again. Where the heck is that sensor that tells the windows to do this? Any ideas on how to fix this issue?

Any help would be greatly appreciated.
