Thanks for your replies
Ya I've found ID for possible positioning and as I've tested to inject. Nothing happens so that could possibly be excluded for controlling.
I too thought that there probably isn't can I'd assigned for driver window since there's probably no use for that, but there actually is a function trigger for windows. That is when using keyfob alarm/dis-alarm buttons, I'm able to run both up and down both windows.
Interestingingly, when I record bus data traffic while pressing and holding fob button and windows are running and then replaying that into the bus, nothing happens.
So I assume there is a ID (or few separate IDs which depend on each others data), for triggering driver window as well.
I think it's probably tricky to find it, or de-puzzle the combo between those utter unknown IDs :/
