Home-made Window Module

Ok,

First post people and I'm having to ask for help. Anyway here's my idea and I was just wondering if someone could help me out with a schematic or something. It's a custom window module with up and down feature hooked up to ONE button.

I want them to go up when as signal is recieved from the alarm (separate button, trunk release). Then when they go up to the top they will be deactivated by a piece of metal on the top of the window completing a circut to turn a relay off.

Now, here's the hard bit, I also want it to go down if I push the SAME button, I want them to go down. Using another contact to stop them.

I don't have a problem with having to push the button twice for it to go up or down if it's in the other position.

So can anyone help me? Also two other things, I want it to be as cheap as possible (ie. as few relays). Also, if anyone can help me out with a shock trigger to stop it when it gets to the top or bottom without a contact that'd be great but not necessary for this circut.

Hope someone can help me!

Thanks, Lewis

he has a point...you would have to get it to continue operation after the pulse completed, ok so you could use a validity output with that (thats how i did my first sunroof)  but you would manually have to stop it.....I just used a DEI *451 door lock mod...but its really just two relays...one for up one for down and I have to hold the button the entire time.....

as for stopping at the top, you would have to use either a pin switch, or mabyee a magnetic reed switch....something like that, but you could get a real window module from dei  (the 1 window 2 way ) for like 50 or so I think....

i did this. it cost me about $10.  beat that!

it's cool.  i didn't make it one touch operation so you'd hafta do some modification.    if you can find a very specific type of latching relay, it'll be simpler.  basically it takes 6 SPDT realys to alternate the signal  these relay are responsible for sendint a signal to the 'down' relays the first time and the 'down' relays the second time the button is pressed.  my alarm is setup for validity output - meaning the windows move as long as the button is held.  if you're willing to do the work to add sensors for when the window reaches either end, it shouldn't be that difficult.  it will simpley be a matter of wiring some additional relays to cut power to the windows when the sensor is tripper.

the other 4 relays i used were for the window motors themselves.  you must confirm the setup of your windows though.  my motor leads rest at ground.  meaning when none of the switches in the car for the windows are pressed, both leads of the motor are connected to ground.  in some vehicles both leads may be connected to nothing whe at rest (floating).  basically i used one relay per window per direction (2 windows x 2 directions).   be sure to use high amperage automotovie relays for this part.  you should be able to figure out the wiring for these 4 relays.  if not i'd highly discourage you from trying to do this yourself.

for the 6 relays alternating the signal, look on the special apps page of the relays section.  there will be a setup called 'latching relay'.  you want the one with 5 relays.  examine it carefully and make sure you understand what is happening.  the momentary switch will replaced by your alarm (-) output.  if you notice, the output of the 5relay setup will send out a +12 signal the first time the signal is sent and continue to after the signal has ceased.  the next time the signal is sent, there will be no output until the signal is sent a 3rd time.  this 'latched' output will be used to control the 6th spdt relay.  the common for the relay will be wired to your alarm output.  the two outputs (87 & 87a) will go to the 'up' and 'down' relays on the motor leads themselves.  the coil of the 6th relay will be connected to ground and the output form the 5 relay setup.  that's it.  if you understand what is going on and how the signal is being redirected betwen the 'up' relays and 'down' relays then you're all set.  this is the setup i used and have had no problems.  for parts checkout www.hosfelt.com and www.partsexpress.com  hosfelt has lots've low current relays for cheap.  for the 6 for the signal you want some small ones to save space and since you don't need them to handle high current.  for the power relays (4) get the automotive relays from parts express.  they've got them for $1-2 which is cheaper than you'll find anywhere else.   that should be all you need.  lemme know how it goes.  special thanks to go2pac and the12volt for all the info when i did mine!

idk if someone will sell you a window module for $10 then go for it

anybody?

There are various options that you can take on this, but I find that my time is limited & trying to wire up 6 relays to accomplish what a module will do in less time will be more beneficial to the customer and even to myslef if I were to be installing this type of set up in my own vehicle. Definitely the options are there so choose your pleasure

This is not fair, but my cost is less than $ 10 for one of the modules but I'm a dealer too . Not that I'll be selling these for less than $ 10.00 but not much more than that.

lol wow from what i've seen them for, there must be kind've a lot of markup then... 

it's all good though, you're paying for a quality product and not having to worry about some've the tedious wiring
