06 QX56 - No hot air through rear zone vents but cool air works fine

So i dont get any hot air (no air at all) through the rear air vents when its set to heat. cold air seems to work just fine though.

Also, the vents in front dont seem to have very much power but they do blow both cold and hot air... i just would expect a significant amount more when set to high.

any ideas?

fan could be on its slow death bead. the resistor wears out. sometimes some debris can get into the contract behind the fan speed switch. info about this on the interwebs.

check plumbing to the rear ac. lines run under the car and between the frame and bottom of the car.
