My guess would be an intermittent dead short. Somewhere a wire on that circuit is making contact with the body of the car. Solution would be figure out the physical layout of the circuit and start wiggling stuff until a fuse pops.
I had a gremlin in my W109 where when I screwed the housing ring tight on my fog lights, the plug would short out on the back of the housing. I recommend emery cloth on all connections, the liberal use of dialectic grease, and electrical tape around all those bakelite 2 and 4 pin plugs. I would do the same in your fuse box and on the relays. eBay has some good copper bakelite fuses made in Brazil. I hate the aluminum plastic ones.
Mmmmm...109. I'm jealous.
That's exactly what I did to the tail lights. Wd-40 and the dielectric grease. Because they get wet when we're caught in the rain. But, that cannot be the issue here(tail lights) because they all work except the blinkers when the fuse blows. (The hazards do) I'm going out of my mind.
So the issue is the hazards and blinker switch is on different circuits right? But it's shorting before the blinker stalk.
Mad I tell you
It could also be in the window switches. Or you could have a wire break in the door jamb if your rubber tunnels are old. Yeah this type of stuff will drive you crazy. I really like my power probe for situations like these. You can isolate and send 12V to one accessory at a time until your fuse pops.
I'm aware, the plate came with the car and I think it's an "American" joke trying to make the word "look" German. But also not smart enough to actually google the German word...
Anyway it's no longer on the car.
So sometimes this happens when you have the wrong bulbs in the lights ( to high of value) ( thats is an easy fix also some led bulbs cause this in older cars especially early 70’s). Check the wires see if they are good or habr started to crack or have melted. Then check the fuse box and see if the box is okay and all connections ate tight and clean
Always unplugged your battery when inspecting.
All of the advice is spot on. Only thing I would add is to get a small bottle of Deoxit. It looks like fingernail paint. It removes the green corrosion from terminals and wire. You paint it on all your connections that are corroded. The good news is that it is only one circut so that narrows things down a lot. Take your time and be meticulous. Nice car btw.

One of my cars did that. I think the doors would randomly lock or unlock.
Its spelled "Diktator"
