UPDATE
Installed a new fan (just the left w/motor) and that issue is resolved. The swap was easy, fast and surprise-free.

The new fan is by Vemo; smooth and silent. The old fan felt "lumpy" when rotated by hand, as if like-pole magnets were moving over each other offering resistance to motion in any direction. That is the only way I can describe it.

The new fan responded to the voltages reflected n the CCU, turning on briefly on engine start and then for longer duration when coolant temp reached 215 degrees and/or refrigerant pressure reached 14 bar.

That said, I still am having A/C cooling issues, but as the ambient temp was only in the 60's last night, when I installed the fan, I could not really test it.

Also, because I am still getting the anomalous values for the (20) Aux Fan control Status Code -- and because, when force-started via the CCU, they spin at an insane speed and made a sound I never again want to hear, I am suspecting the fan control module may also need attention.
