I hate that our power windows only have auto down on the driver side and don't have auto up. What would it take to add this feature? Is it in the switches themselves of does something else cause it to do it?

Thoughts, ideas or ever smart ass remarks are welcomed. Thanks

Re: Auto up and down?

I agree Jesse

I know in my 92 Talon Tsi it was a simple mod to make it work.

But who knows what kind of chaos this would cause with the BCM

Re: Auto up and down?

So it wouldn't be as simple as just replacing the switch then? I had a feeling it wouldn't be that simple.

Re: Auto up and down?

Not sure, but there's probably a switch or position sensor on the driver's window at the bottom position to tell the BCM when the window is fully down.

If so, when in auto-down mode the BCM runs the window in that direction until it receives the input from the sensor.

For auto-up you would need at minimum a sensor to "see" when the glass is at the top.
(which could be mounted at the bottom of the glass, which would be easier than trying to put one at the top)
Then you would either need additional programming in the BCM or a separate control circuit. A separate circuit would be much more practical.

Of course you could just have the control run the window up for a time period (greater than the max time required from bottom) but that would be a bit hard on the mechanism over time.

I don't even want to speculate here. Maybe James would have some insight on this topic

Thats what I was thinking, thanks Jeremy.

Re: Auto up and down?

One of my fantasy mods includes exactly that, and..

I have a favorite position for the two front windows about 5 inches from the bottom where I can drive at highway speeds and the wind doesn't buffet much.
But then I'm a little OCD about getting both the driver's and passenger side to the same height.

If I ever had time I'd install position sensors at that level also and a button to tell them to both go to that position.
But then, I'd have to either learn to add signals to the buss (to communicate to both window regulators) or be able to run additional wires into the doors.

Stupid, I know and I'll never get there but its something I ponder on long road trips from time to time.

Haha, guess I'm not the only to think about this then.

Re: Auto up and down?

Other than the switches, most of the window control, including the auto down, is performed by the logic board in the Driver's door switch module. The logic board monitors the motor armature current. When the window reaches an up or down stop, the current increases and the logic board cuts power to the motor. That is also how the window is stopped if something is trapped in the opening while the window is closing. It will also cause a window to stop moving if the mechanism/glass gets jammed.

Well that makes total sense... and eliminates the need for a (separate) end-of-travel sensor.

That being the case, with the addition of a switch to command it and a little additional circuitry you could do the same for auto-up.
Could possibly mod the existing circuit to sense the stalled current in both directions, else you'd have to duplicate the current sensing circuit for the up direction.

I suspect the manufacturers are squeamish about liability, in case a kid sticks his head into the window and his brother decides it'd be fun to mess with him.

Bump for some more insight on this, or at least some to explain it to me in English. :lol:

Any smart ass comments lol. I'm crank and I'll be converting to power windas. I should ask the vender when I buy em if it has the auto up and down within the kit they'll sell me. I'm sure it won't but hell it's worth a shot.

They actually make a kit that goes behind the crack so you don't have to figure out what to put in it's place. You just push the crank down to roll down and pull up to roll them up. They make them for the older cars that want to keep the chrome cranks to look stock. I'm sure those will have the same option. I bought them once for my old car but never got around to putting it in, forgot all about this company till Rich brought it up.
