Passenger Window only works under specific circumstances...?

[HONtoBMW]

2002 525i
Passenger window only rolls up and down manually by turning my lights on, and rolling the interior dash and radio “light strength” dial all the way up. Also, the order of those events have to be in that exact order or the window doesn’t work.
When I start the car and try the window it’ll roll down by itself and won’t go back up unless I follow the above steps in order.
Been searching the forums but this seems like a very specific issue.
Thanks!

What is the battery voltage when this occurs?

Also, when this occurs, turn on the passenger visor light. If it has an affect, the iggy switch is likely bad.

Voltage on startup is around 12.4
When I try to roll it up/down it doesn’t fluctuate.
Only when I do the lights+dial and roll it down does the voltage change, which I figure is normal.
I’ll try the visor light and let you know what happens.

Alright, operating voltage is 13.4-13.6.
Visor light has no effect
