New Window Regulator - Sounds Bad When Door CLoses

[shacky]

I had local Porsche Mechanic put my new passenger side window regulator in. He told me it was a challenging job. All seemed great until my wife got in and closed the door with the window down. Sounded like the window crashed! If window is in up position there's no problem. Closing door while down sounds like something is very loose.

Any ideas?
