driver's side defrost vent not blowing

Hi - just wondering if anyone could point me in the right direction

My driver's side defrost vent (for the windshield) is not blowing air. All other vents work fine. Im assuming that the
connection for the non-working vent has detached or something... how would I check for this and fix it???

Thanks in advance
Myles
