Darrell drop your front bumper and look over to where the bottom door hinge is there should be a box built around it and sealed up good.

If that lower hinge enclosure is compromised it will cause a draft.

Also the control for outside air or recirculate leaks like a screen door on a submarine, even on recirculate it is still letting in much hot air. The damper sucks.

While the bumper is down you can tape up that intake it is on the upper edge of the bumper compartment. Duct tape 10 inches.
