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.
That makes sense. When I was searching the part, GM was calling it a Vent Valve.

If all else fails, pick up a sheet of thin gauge steel or Lexan from Home Depot and build your own.

Or head to a salvage yard. The blank panels are going to be far and few between since the 2 doors were so uncommon. But a 4 door version should work. And if you want to make it like original, cover the back with Gorilla duct tape.

I was able to find them used but couldn't find anything new either flat or vented. Parts yard it is. I hate buying 20 year old plastic.

The odd thing with the blank plates is that they'd be susceptible to flex every time you closed the door. They have a very small border for the screw hole that could easily break. I think I'll go with the vents instead of the blank unless someone knows of a downside? It seems to be something GM would do simply for cost reduction on the 2drs.
