Default Power Window Issues

Hello, I'm having trouble with my power windows in my 1972 Stingray. I just acquired this car at the end of June, so I'm starting and trying to learn more and more about it.
A few weeks ago, I had the driver side coming up and down slowly. The passenger side was working fine. Then the they both stopped working last week. I have been doing doing some research on troubleshooting, but I guess I'm trying to understand how or why both would stop working. I looked at the fuse box, but don't see a specific fuse for just the windows to verify it wasn't a blown fuse. The labeling on the box is old so, I may have missed it. Is there a fuse for the power to these windows? Is there another power source. Any feedback would be greatly appreciated. TIA!

There isn't a fuse for the PW, there is an auto-reseting circuit breaker out on the firewall instead
Here's the circuit



The connection to the fuse panel is a pink with black stripe wire that plus into the ignition terminal in the center of the fuse panel, you can see it here on the left side near the bottom



First thing I'd check would be to make sure that is plugged fully in
Then I'd check to make sure you have power going to and through that circuit breaker. On the 72 it is located just above where the vacuum lines and wires come out, just around the corner from the brake master


Should have power on both sides regardless of the key position

If there's power there, the next part is harder. The PW relay is located under the center console, if both windows are not working at all, that would be the next place that needs to be looked at.
You can sort of check it slightly easier by removing the park brake console and testing the switches, the brown or red/white should have power with the key in the run position, if they don't then the relay is the problem, if they do then check the switches, and finally the motors

Oh, one more thing before you get too deep, check your turn signal flashers and your reverse lights. if they aren't working you might have blown the fuse that feeds the IGN connection on the fuse panel, I believe it's the bottom or second bottom on the left row of fuses

I have the console off doing carpet and trying to fix this issue. The breaker on the firewall is fine and has power on both sides. All my other lights and stuff are working fine. It is just that the pink wire from the fuse box does not have power. If I put power to it with my probe the relay clicks and the windows work. I am probably just going to run a wire from the extra switched power from the fuse box to get them working.

Thanks for the fuse box picture. The pink wire was not plugged in for some reason and was tucked up where I could not see it. Problem solved. Thanks everyone.
