I would think the switch is bad.....
But double check continuity between a/f when pressing the switch up and check the other switch to make sure it’s not backwards or something, or upside down.
Whoever molested mine In the past put them in upside down in my car, then I plugged them in backwards and had no idea what was going on... at first

Yes, for the up and down continuity tests, you need to actuate the buttons as described. Per your chart: push left side control up and the continuity should exist between a-f and also b-e. push left side control down and you should see continuity with b-e and c-f.
Edit: Should add, if you do find missing continuity, don't throw the switch away, just fix it. They are plastic press fit together and come apart easily for inspection and reconditioning. Here's what my 83 switches look like inside, you just clean up the burned contact points.
and consider the power window relay upgrade wich vastly reduced the current handled by the switches, relegating it to relays which are better suited and easily replaceable.
