Advisable to block off outside ducting..
Pros and cons of blocking passenger side recirculation duct work...I live in Michigan and will be a summer only driver and I am looking to mitigate inside heat.
AC car, but invariably will need heat occasionally.

Your heater core is on the passenger side, so if you block off air from coming in, you will have no heat. Of course the coolant will circulate, but the air to air exchange will not happen, at least not as efficiently. But it does depend on where you are blocking off. If you simply block the outlets on the lower inside side panel and the ball, ......then you would still have heat.
Is my vette stock?? HAHA

It would seem to me that you’d want that door open for the air that comes through the car which should be cooler than the air you would be sucking off the floor of your car, unless in max ac mode..?
this is what I just learned about that door. What your car do you have?
I agree I’m in Indiana and I love my heat even nighttime spring and fall even in the winter with no snow or salt not to mention defrosting to see or to roll the windows down and have the heat on like yesterday. It’s good to have options

That recirc door in the right kick panel WILL block off incoming air IF you replace the worn-out seal on it and the system is working as intended. You can DIY that door with some pop-rivets and a new seal made out of 1/8" thick sheet of black craft foam purchased at hobby stores (or on-line). That stuff is IDENTICAL to what was originally used for the seals.
P.S. To remove that door, just pull UP on the spring-loaded pivot pin at the top of the door.
