Blend Doors

[BigDaddy02RAM]

I have a 2002 Dodge Ram 1500 slt 5.9l Crew Cab. My issues is when I turn my a/c on, it blows cold on driver but hot on passenger side. I know it's not the recirculating blend door. Which door could it be? I already know it's going to be a hard job.
Thanks

Dual zone climate?

There isn't an option to switch to passenger side or driver side.
It's all in one.

Ugh so much for easy....when the temp mismatch happens side to side, is air still coming out consistently on both sides? Or does it feel like it's somewhat blocked or no air flow?

The blow strength is still the same.
I know there's 5 blend doors.
I know definitely it's not the recirculating blend door blend because it blows with whatever I choose. Like on your feet...
