Power window controllers

[parsonsj]

Hi guys,

I've got a customer car with 4 power windows with just the power leads coming to the center console (reverse polarity motors). I'd like to wire the window switches through relays and I don't really need one-touch (though it would be nice). That's 8 relays...

I'm wondering if anybody knows of a solid/state 8 relay module that would be suitable for this? The other problem is that I'd like to have some kind of programmable stop for the down position. The factory stops are too low, and the travel mechanism makes a "popping" noise down there that I find annoying.

thanks!

Move the stops, there is no sane way to do what you are proposing.

What are the window switches and why do they need relays?

[parsonsj]

The switches need relays to reverse the polarity. Perhaps I'm spoiled by using a lot of InfinityBox gear, but I really don't like to run more than an amp or two through a switch. And when you only run ground circuits on the 85/86 side of a relay, you can use any switch you want. No need for a 15A rated switch...

As far as the stops go, it's the back windows in a 69 Camaro. There's no good / easy way of doing that. You're pretty much limited to the base window regulator geometry... unless I'm missing something.

Here you go- a good - easy -clean way. No micro/mini/limit switches needed.

This piece has 8 inputs- and 4 programmable outputs. Designed to handle linear actuators- so you can completely control the rear motors.

PAC TR12

I'd mount it at the switches-less than a couple hundred mA- then run a couple trigger wires and power to each window- put a couple Bosch relays at each window-done!

Uses a USB to program-

Less than $40

Richard,

I like it. I'll put the relays under the dash, treat the rear windows as a linear actuator, and put a timer on down. Thanks very much!

I can even make the windows one-touch where you "tap" the switch to start them, then tap again to stop.

Very cool.

Now then: anybody know of a cool packaging setup for 8 relays? I've used this and this in the past, but I was hoping for something with solid state relays and a single input/output harness. I know I've seen something like that, but I can't remember where I saw it.

[dontlifttoshift]

Oh, so you have the wrong switches.

The ISO 280 micro relays and the individual bases that snap together take up the least amount of space if you don't find the solid state set up you are looking for.

[parsonsj]

Oh, so you have the wrong switches.

I don't have any switches, lol!! Just the power connections to the motors. Which work fine when tested with my Ridgid 12v cordless drill battery.

I really like using the ISO 280 micro relays. I did find this (overkill, but whatever):

8 micro relays, fuses, etc. It's packaging is decent and clean. Asking customer if he wants to pay for it now...

[Richard454]

I've become a fan of these- might not be the ticket for your project- but excellent for configuring some extra circuits.

Then the LED indicator fuses- and you are good to go.

John, which power window system does the customers car have in it now?

Back windows are Nu-Relics. Not sure about front. They all work fine when directly manipulated.

[H2Ogbodies]

I can supply you with auto down and up using those reverse polarity motors. I do stock the 280 series relay too.

[H2Ogbodies]

Something like this splice kit-only with smaller relays/bases. This is a direct splice auto down/up relay kit for 2 windows.

John:

This is another option from Eaton that houses 5 280 micro relays and 10 mini fuses. It has a water-proof cover with a tether.

I had one of these for windows, might work here https://www.ronfrancis.com/prodinfo.asp?number=BX-10

A pair of Directed Electronics 535T window modules will do everything your looking for and more. PM me if you need more details.

You're missing something. There should be a positive stop for the bottom of the window travel.

[parsonsj]

You're missing something. There should be a positive stop for the bottom of the window travel.

The factory positive stop leaves the window an inch too low, so that the window can get stuck in the felt or the outside wipe. Bending or altering that stop will work for a while, but power windows will eventually push down that sheet metal stop if the driver just holds the down button to when the window mechanically stops.



InfinityBox's inMOTION does a nice job of using current use as a guide for when to stop the windows, and I've had good look with that. But I don't have an InfinityBox setup on this car, so I was looking for something like that.

Chuck: that Ron Francis kit was the one I was thinking of. I see it's now on indefinite backorder! Bummer.

[dontlifttoshift]

It's on backorder because it doesn't work.

[parsonsj]

It's on backorder because it doesn't work.

Oh. Well then... glad I don't have one.

I use solid state modules-the IC uses resistance (ie window suddenly slowing down or stopping while travelling) to sense when to close. It won’t matter where your stops are-you can move them to wear you’d like and the modules win’t allow the window to “try” and move any further down from that point.
