Dealer wasn't able to replicate so no fix as no issue was observed (the fans stayed constant). No error faults were found in the system.
Just looking at all the information versus what's in Ford's workshop manual (Thanks again, @Haz), there is conflicting information.
Ford is saying the TED is still used but as people have pulled the seats apart, they are only seeing fans...and the heating function definitely does not use these seat fans, from my own observations.
Maybe the SMCE is still monitoring temps and that's why it's changing one of the fan's speed...I have no idea.
The heating function definitely does not use the blowers, so Ford's literature is outdated on that from what I can tell, which means any Ford Technician referencing that is being led astray.
Sounds like I will just have to live with it.
