As the spooge drains out the drip dray vent , I'd not quit yet ~ I can still see lots of crud in the fins and that reduces efficiency greatly .
Maybe vacuum with the soft uphosterey brush ? .

(Symptoms: won't start unless you give it full blast power far left button, then it will work OK at all speeds once rotating.) Took it to an alternator shop to have them put new brushes in it. Technically, it is not set up for user repair but I believe new brushes is do-able. Will let y'all know as soon as I get the word from the alternator repair guys.

The only way to get the motor out is by removing that hose. Good thing my a/c is freon-free at the moment LOL. Nobody ever told me of that little issue. If you are working on your a/c in one of these cars, consider new brushes in your motor while you have your freon out. Once I got the motor out, it was apparent that the brushes were about gone. So it appears that the diagnosis was correct.

I went to my local Toyota dealer and got their evaporator cleaner kit for $20, and sprayed the evaporator out with it. I used a soft toothbrush very lightly on it between sprays, up and down with the grain, those vanes are delicate. That kit will fill up the evap box with foam about four times. The foam then condenses and drips out of the condensation tube, really dirty. At first the toothbrush was black with crud but by the third foaming, it was pretty clean.

Comparing the two videos, it looks like I took 20 years of crud off by using the cleaner. Not like brand new, but 75% or more of the way there. Close enough I hope. Now if the guys at the alternator shop have good luck with my blower motor, I'll be set.
