I thought about this riddle more ;
I think you have 3 circuits here
1 headlight switch That turns on supply power to the headlight relay, then your lights go on and they will go to either high or low beam whichever they were left in last.
The reason they go to where they were left is because that’s how the relay was left and until it gets a pulse from you pulling the switch it will remain like that it’s mechanically in that position
2 the switch on your column, you pull that and provided your lights are I on it will switch the Special relay to high beam low beam high beam low beam Etc it’s changing the set of contacts being fed power each time it gets a pulse the relay has two positions .
3 when you pull that switch it Also powers a relay used just for “flashing” another driver
This circuit is not running your headlights not really , it’s only function is to turn them on for a moment when you release they go out that will be run off it’s own relay and that relay will always be supplied power even when your headlights are turned off
Circuit 3 works and so does your column switch
Your relay isn’t switching to high beam and low beam I suspect that relay has an issue
I do not think that column switch is bad because you proved it works because it will turn on the flash function
I’d want to know what’s happening at the high low relay and I think I’d try to locate that see if it has power when the lights are on see if it gets a momentary pulse when you pull the column switch it should be clicking and powering either the low or high beam circuit alternately
I might be off in some if this but that’s how I see the issue
One thing that did not make sense how quickly can the headlights open ? Does pulling the flash function also open them ? It must
I think there are some contacts around the motor and the lights need to open to be seen
Maybe when the lights get power it causes the motor to move so then they would just open and close when you released that flash function

If you look at the wiring diagram, no relay involved in high beam/low beam switching. All handled inside the switch.
