2019 RAM Big Horn 4x4 w/Cummins and single zone AC with knobs.

AC blows heat, not like warm air, but heat.

I can see when ac is on that, the box starts sweating, and AC is condensation under the truck.

I think it’s the blend door actuator.

Does anyone know where this is located on the 5th Gens?

I know the fourth Gens was behind the glove box, but I pulled mine, which isn’t there.

Any help would be greatly appreciated!!

Also, if you think it may be a different issue, any help would be greatly appreciated.

Thank you, guys!
