AC/heater fans totally dead

First off, I am not concerned with the a/c components at this time. I will deal with that if and when I get the fan to work. I think I will be looking forward to heat long before I get to replacing a/c hardware.

I am starting on the passanger side
(US) fan because it’s the easiest to access. The fan assembly is still in the car because the two cables have the fan captured. That is why I need to know how to remove the
male/female connectors from their mounting bracket which is riveted to the fan case. These cables do not connect to the fan, they are just secured to the fan box. As a foot note, my car does not have a glove box in the dash. Everything is accessible by removing the under dash cover.
I do have a photo of the offending cables
but I don’t know how to attach it to my comments. Also I don’t know about a “flag”
bur I will try to find out.
Thanks for your input.
