Question: Power Windows after shut off?

[papp]

K, I'm an avid member over at www.MP3Car.com, and I figure you guys can help me out with something. I'll try to make this short.

We use shutdown controllers to keep a switch (relay) to the battery open for about 15 seconds after you turn off the car. I don't want to spend the $$$ on one, so I've been thinking.

When I got out today, I remembered the feature of using the power windows after you turn off the car - say, if you forgot to roll your window up after turning off the ignition.

What I'd like to know, is if anyone is aware of how exactly that system works? Is the power available to the windows after every shutoff of the ignition? Or only when it senses that the windows are down? And finally, how long does it supply power to the system after shutoff if I do not touch any of the buttons?

Sorry about the long explanation, I love the threads here on the QUEST FOR HIGHER MPG!

The truck never knows what state the windows are in (down or up). You have the ability to roll down/up windows after ignition is turned off, until someone opens the door, or a time is reached. The time-out is far longer than 15 seconds, but i don't know how long exactly.

Thx for the quick reply. So it works until the door is opened? Does anyone know if there's a way to take away the door sensor so there's only the timer going?

Any other info on it would be great. Thanks guys!

From taking a quick look at the schematic, the timing circuit looks to be controlled by the GEM. I can't see where it is controlled by a simple external timing circuit.

pffff, duct tape over the door pin

does anyone know if there would be a drain on the battery during this ten minutes other than what i have installed?

radio works that way also. stays on for like 30 minutes..

I have a 12v lcd screen, and a 150w power inverter.

I don't know what's different about my radio, as it turns off right away.

Perhaps there's a setting somewhere. . .

on my 2002 as long as i do not open the door the radio stays on for a long time..

You should be able to operate your windows.
( until you open the doors )
