I've been looking really hard into this, cos it effects me more than most I suppose. See when we convert your trucks from left hand drive to right hand drive (for Australian conditions) all that we generally do with the door controls (window, door lock etc) is extend the loom and move the existing switch module from the LH door to the RH door to suit our driving position. It all still works fine, but this now puts the express down button as the button closest to the driver and it now works the passenger window (make sense?). Generally we would have this feature disabled rather than only have it work on the passenger side window.
So in looking at some options and following a hint from Wiki, I looked at the features on other GM type vehicles.
It turns out (according to the web sites) that cadillac have several models that feature express down on all windows - the CTS, seville and deville. How handy it would be if the Escalade or Escalade EXT had this feature,'cos it would be a straight swap right?
Soooo, what I want to know is why (according to the respective web sites) the US Cadillac Ecsalade Ext doesn't have express down on other windows BUT the Canadian Cadillac Escalade EXT does!!
What's going on here then? It proves a bit hard for me to nick down to the local dealer and have a look, you know $1,800.00 dollars and a 20 hour flight later.
So I was really hoping that someone a bit closer to the action (like from Nth America somewhere)
could confirm or refute the above information.
