Window ECU wanted with glass drops slighly before door open
Discussion
I have a 1997 cabriolet where the door glass drops slightly when/before the door is opened *
But the window ecu (from Rockwell) no longer functions - and is no longer available.
What other cars have this feature? And the ECU is separate (rather than incorporated with the window motor).
I'm looking to see is an alternative part could be used.
The peugeot 307cc has the feature, but it seems to be incorporated with the motor.
Ot does anyone have a circuit diagram for how to make one?
( * Does anyone know what this feaure should be called? )

Hi @mmm-five, is there a problem with only asking a Q ocasionally. But ... you did deduce the car correctly 
Of course not, but it makes it look like you'd post a question and then never come back with follow-ups or resolutions....and this is why I don't put money on any of my bets
With ignition on, top relays are energised and window motor circuit is as standard
With ignition off, dropper circuit is operational
The operation/procedure for using this Dropper/Lifter circuit is as follows
1) Door in unlocked position - Drop the window to clear the Targa Top and exit vehicle
2) Close and lock door with key
3) Operate the Drop/Lift Button - Window Lifts (Will be posting some options for the button/other methods later)
On returning to vehicle
4) Unlock door with key
5) Operate the Drop/Lift Button - Window Drops
6) Open door and in you get
5 wire CLS Actuator needs linking to door lock unlock button/mechanism
Drop lift button can be replaced with a momentary remote control device
Or
A hidden button can be fitted somewhere, I like the idea of a button fitted to the bottom of the door mirror, a Reed switch can be fitted inside a screen or panel and be operated with a magnet on a key-ring
Modifying the key-lock barrel to operate a micro-switch or fitting a micro-switch to the door handle are other methods - A bit of thought and engineering
There are numerous ways of going about switching this simple circuit
