window goes down when door opens

Does Anyone have any Idea How to make my window go down when the door is open and go back up when the door is closed in or just make it go down once the door open ? (thats the important part).

And what relays or interface i will need. Just a diagram would help also.

I want to  do this for each door and its mating window.

Please Help??????

Thank you.

i would like the window to go all the way down when i open that door and up agaain once i close the door. the purpose of this is i have lambo doors on the back doors of the car and when they go vertical the window hits the front doors and could break. so far the only way to avoid this is to open the front door before the rear is open. once the window is rolled down it out the way. i will try the 530t and see what comes from it.

if you could draw something up id appreciate it. thanks everyone.

I think ive figured it out useing the 530t and the grounded door pin from each door. i will draw it out and post it asap. if any one comes up with something pleaase post. thanks to everyones input so far.

Well here goes. I drew a digram. please look at it and let me know if this is wrong or will work.

keep in mind that with this diagram both windows will go down if the door either open and both go up if  either door are closed. it is not what i wanted but i have figured it out using 2 530t's. and will post diagram once drawn up. just wanted the guru's to approve this one. PLEASE LOOK AT IT. I appreciate everyones feed back.

I cant upload the diagram! its too large i i dont know how to shrink it. SORRY.

ANY WAY  everything is wired the same way as in the guide. EXcept for wire h2/3 ( RED / white) which is the aux. input i wired that to the door pin instead of the alarm as i dont want to use the alarm in this function.this will send the windows down when i open the doors and (this next part im not sure of) I wired h2/4 (orange) to the other side of the pin this should send the windows up when the door closes.

please let me know if this would work. thanks all.

I just checked the door pin function on my car. here is how it works.

When the pin switch is pushed in all the way (door Closed) the pin reads 12 volts when the pin is out (doors Open) the voltage drops out and i get continuity with the chasis, meaning it bocomes a ground.  this may hinder my plans

How does this happen and why?

Please help.

Thank You.
