Strange Heating issue

[Zedyone_kenobi]

Just to update guys, I looked under my dash at the DEF cable attach point. I think I found the culprit. When I reran my new choke cables, I got them in right in the way of the retract for the DEF cable. When I pulled back I must have dislodged something in the instrument panel. The cable slides smoothly and the door opens very easily. So I think the center console coming out will show me that I have a broken or dislodged cable. Great detective work.

Thanks for the pics and the help folks. It staggering what you can learn here!

Instead of starting a new thread, I thought I might jump on this one. I have a 71 with A/C and I have heat only coming from one side of the car-right down the middle guys- never seen this one before.

All the heat is coming out the passenger side-BUT air is still blowing where it should be on the driver's side-just not hot. Now I have redone one of these HVAC units for my car, and for the life of me I can't see how this is happening unless the heater core is bad on one side?

Any ideas??
