So you’re saying that you don’t get heat out of the upper vents at the center console rear?
I think @plplplpl may know of some heater control buttons you have to press to get this to work.

You should note that heat only really comes out of the top vents of the center console for the second row if the front mode controls are set to an arrow pointing at the little dude's face.

Otherwise, including on Full Auto, heat comes out of the bottom vent and A/C only comes out of the top vents back there, which kind of makes sense from a thermal dynamics point of view.

Yeah, definitely clean that screen filter even if you’re getting decent air flow. It’s only a matter of time before it clogs up with lint.

front mode control pointed towards the dude face.

rear control turned towards heat (only rear floor heat works)
Rear control turned towards ac (floor and rear ac vent works). Ill clean the filter (where is the filter located)

No, it’s not the same as the cabin air filter. The rear blower filter screen is located behind the removable panel to the right of the driver’s right foot.

@plplplpl has the link to photos of the filter screen.

Also note that the rear heat/AC control knob only works when activated by pushing the RR/AC MANUAL button on the front climate control panel. A little green light just above that button should then indicate the rear Heat/AC control knob is now functional.

You mentioned rear AC air flow is fine. If this is the case then your rear blower motor transistor module is okay for now. Lack of airflow across the module’s cooling fins will lead to its failure so still clean the lint screen at some point.
