I FOUND THE PROBLEM!!! Woo hoo. Still have to reset everything, but... The blend door itself has become disconnected from the drive gears inside...
It was a video of pin test. Hot wired servo on the bench then ran continuity across the 3 pins for the pulses. 1&2, 1&3, 2&3. Checked good. I...

Sadly, the harness did not fix it... Back to bad servo thoughts. I was unable to test the “limit switches“ I think I’ll pull the servo, wire...
Thanks Chapman. I bought the harness and will install tomorrow. I’ll report back with results. Now I understand why that harness is so expensive...

Chapman, Thanks! I do understand the theory of heater core. I appreciate you restating fundamentals though. EV mode is claiming not enough...
