I have been chasing this bug for over a year now.
Slaved rear blower into front system and it blows great.
Replaced the blower resistor
Replaced the electronic controller
Replaced the door actuators
Replaced the drivers overhead controller
Checked under hood and drivers side dash fuses
Performed continuity checks on wiring.

Cannot get this thing to come alive to blow period!
What else is there?
If there is any tribal knowledge at all - ANY I will really appreciate it.

Sounds like the rear controls is bad
