Yes you can as i said is just briging two cables together or replaceing it. i have zero knowledge of electrical stuff or anything of that sort. so i wouldnt know,
but in my logical sence of things (MINE don't do it unless your sure, get a 12v current tester, and check wich cables light up when you press the buttons, or activate the "1 click".
there are at least 3 cables involved.
1 is the cable that when you hit the "1 click" down on the drivers side, it should lite up (get 12v)
2 is the normal cable for the up or down movement for the drivers side (button #1).
3 is the normal movement for the up or down movemente in the passenger side (button #2).
when you press the "one click" 1 and 2 should make the entire circuit, but there is nothing there for 1 and 3, and that is what you should do IMO.
I don't know if you need relays or not. if you don't know about electrical stuff, take them to a shop or ask a friend, he will have a more detailed explination of how things work. (maybe that is why you posted here right???
