-First of all, what models and years have the all around one click windows auto-down on all windows?

-Secondly, what would someone with an older model ('91 in my case) need from a model that has the feature to upgrade to it?

I shouldve searched first maybe :)

I hope I'm not posting this for my own interest only :) lol

It's in the General Module. But when you change it to a newer one some other stuff goes wrong.

Search for it.

I have a 95. They all have one-touch going down, and only driver's side has one touch up.

Yea, I have tried the GM out of a 7 series and also one out of a newer E34 (not sure what year).

While the wiper delay was programable and the windows were all one touch down........

My door locks would immediately lock themselves when unlocked. Same problem with both GM's.

Anyone here sucessfully done this?
