driver side window making noise

[st.augsolara02]

soo i pick my car up from the shop today from gettin an oil change and fuel system cleaning..i pull out and head for home and half way there i decide i'll cruise with the windows down since its a nice day out..i roll down the window and as soon as i gets all the way down i hear this huge thud and the window just fell to the bottom of my door..it comes back up just fine tho but it makes that loud thud everytime u roll it down..anyone have an idea as to what it might be?

i think you have a rubber bumper stop that prevents the window from falling out the bottom of the track. maybe it fell off or was removed.

open up your door and see what it's doing.
