Gasp!!! You fixed it!!
:yoface:
So.........
What's it doing or not doing?
Blower motor coming on?
Can you feel air?
Is it just cold instead of warm?
Are you using the rear controls or the front controls to control the rear?

Blows air just cool air. Heater set to 90. Controlling with rear controls, front set to aux. not sure how to control rear with front controls.
If the front is in aux, that means the rear will be the same as the front.
If your running the front n heat and the rear is still cool, it's probably the blend door acuator

Any idea on location? I ripped apart the rear passenger side. All the diagrams I've see are for NBS and have the actuator sitting there. Mine is no where to be found. Figures.
My chilton doesn't even list it.

Your blend door actuator is dead. 
Time to replace it.

Just an update, it wasn't the blend door actuator, rather the blend door itself was in a nine line bind. Why, I don't know. But I had to split the unit in half to free it up. Returned the $150 actuator, job cost $0. WIN wonder what the mechanic would have charged.
My daughter is glad to have heat now lol
