Hi gang, I've got an issue with my I8 I'm hoping someone has seen before or there is a tech out there that can chime in. The air conditioner works great. But now that it's cold here in Texas, my girl has finally decided to use the heat on the passenger side. NO HEAT!!! She's not a happy camper.

This is what I've diagnosed so far.
The drivers zone works fine, blows hot to cold as per the direction of the knob.
The vents move properly between footwell, dash, and defrost.

The passenger side vents move the air as directed from footwell, to dash, to defrost.
But the temp control does not make the air warm. On cold it is ice cold. On hot it is maybe just above cold.
I replaced the blend door motor, and registered and calibrated the motor with my Foxwell scan tool. It says completed, and there are no faults. but... it just will not get hot on that side of the car. What gives??

Anyone have an idea of what to try? I'm getting frustrated.

thanks
Jordan
