Setup: Third row removed, ARB drawers installed

When doing long drives, usually set climate control to auto and keep the A/C on regardless of outside temperature. It seems the front stays fine, but the rear starts to pump out hot air at some point. This generally seems to start happening when it gets cooler outside than what the setting is. But the air getting pumped in is hot. I can feel the heat down under the floor running right under the shifter/cool box.

My latest work around is taking it off auto, setting the temp to "low", and managing the air flow to control temp.

It seems that maybe it has to do with the rear sensors acting up and/or blocked by the drawers. This has happened both with a fully packed vehicle and nothing in the back.

Anyone else experience anything like this?

My wife wants to take it in. I dont think they'll find anything that will be of help. So i figured I would see if anyone else experiences this.
 
Something I haven’t been clear on for a while, and I feel like I should know this.

Are the little plastic covers with a resistor-looking part inside, in the little cubbies for the third row, the rear AC temp sensors?

I can get a picture of mine if no one knows what I’m talking about.

Yes.

It is my understanding that those are in fact the sensors.
