That makes sense. When I was searching the part, GM was calling it a Vent Valve.Ah, good point. Mine has the same blank plate while my truck has the vent. Number for truck left vent is
15718115.
On my Tahoe (2-door) there is a door vent in the metal door panel that has a flap inside it. On my truck, that door panel vent was non-functional and covered by the waterproofing plastic. It has the door vent on the outside.
I guess there’s a reason for it somewhere, lol. Maybe cab volume if I had to guess.
