Express Down On All Windows

I like the thought of Express down on all the windows. With that said...

Do not put in a express Up feature if you have small kids... A friend of mine a number of years ago lost his son when he left the key in the truck so the tape could keep playing in the radio.... he went to look at a broken fence.. the son lenned out.. foot hit the button and the window closed on his sons throat. He was dead from the crushed windpipe and my firnd could do noting to save him even tho he was there quickly. The damage was done.

I know do not leave the keys in the truck is the number one issue... but we all have done it for the radio or other reasons.

Some vehicles have express up.... but be careful. Larry has still never forgiven himself... even after 15 years. His son would have been a senior in Highschool this year.

A reminder... this was a vehicle 15 years ago. It did not have a sensor to stop the up movement if something was in the window. I know there are a number of ways to prevent this now... Just be careful... thats all.

The modification you are talking about would prove very costly due to the systems involved. It is not as simple as changing the switches. The door locks and window system works like a computer network. They talk to each other over a class 2 network comunication system. The drivers side door module(DDM) and the passengers side door module(PDM) are virtually identical on the inside, but each perform very different functions. The DDM controls the windows and the door locks of the entire vehicle. The PDM controls the remote keyless entry system and on the 2004s the Tire Pressure Monitoring System(TPM). For the modification you are talking about you would have to change both modules and then program them to work with your system The Truck Body Controler(TBC) looks for a specific part number PDM and DDM they also have the VIN burnt into them. To make the conversion work you would have to have the dealer use a TECH 2 to reprogram the entire system. I believe it could be done but like i said before it would be expencive.

I don't want to get off topic but this is important and can't be stressed enough: Leaving kids in the car/ truck is just a bad idea, especially if 1) you don't set the parking brake, 2) you don't put on the window lock, 3) the children have not been taught to stay in their child seats and seatbelts, and 4) you aren't in the truck. Kids watch what their parents do and want to imitate them, including turning the ignition, moving the gearshift and releasing the parking brake. I have defended more than one manufacturer against claims that began when a parent left their child unattended in a vehicle.

Jeremy, that is a super informative post for someone so new to the board. Sounds like you have got a lot of experience / knowledge in this area... what do you do for a job?

I have a few real specific questions I'd like to ask someone who is knowledgable in all this stuff.... you sound like a good candidate. ;)

I remember releasing a parking brake when I was a kid, I also took it out of park. No, the engine wasn't running. The car ended up across the street, and I ended up getting my bottom warmed really good, but I did get my marble......I know a little off topic.

I would like to see more posts from jeremy, a little on his background.

This was something that in the end I didn't pursue as the 2003 av's have express down on both front windows which was enough for me.

I never did resolve why (according to the websites) the Canadian EXT has express down on all four windows but the USA one doesn't.

This is the switch block from the 2003 EXT... does it look the same as the av?
window_ext.jpg

err... a little late ;D, but to answer your question, yes, the 2003 Av's driver's switches look just like that.
 
Well

i now have a new 2003 2500 Av along with a 2003 Yukon XL Denali


The plan is to use my denali window switches as guinee pigs and try to take the front window switches and install them on the rear switches of the av, and just see what happens

If it works, i will inform

actually - either way I will inform

Later

Yeah... I've since taken delivery of my av, so now I know the answer to the question. Before that I had only ever seen photos of them. :rolleyes:

I don't know where you get the idea that the Canadian Version of the EXT has express down windows on all 4 windows. According to the Canadian GM website, they don't... I have not looked at one personally, as the dealers around here never seem to have 1 in stock when I look....

Off the website ... http://gmcanada.com/english/vehicles/cadillac/ext/ext_details.html

Windows - Power with express-down feature on driver's side and passenger

This is only indicating the front windows....

Chris,

This info originally came from me and was based on the Canadian 2002 Escalade (not EXT). I can assure you that the website did say for 2002 models that they had express down on all 4 windows... I note now that the 2003 only says the front windows are express down.

Of course it could be that it was a typo all along. :(
 
For example here is the info from the CTS...

Windows - Power with express-down on all windows and express-up with pinch guard on front and lock-out on rear windows.

CTS details

Interesting to compare to the DeVille...

Windows - Power with express-up and down feature on front windows and express-down feature on rear windows with window lock-out

Good info... That brings up a another example of differences between the 2002 and 2003... I do not believe the 2002 switches will work with the 2003.. I could be wrong, but I think the 2002 did not have the DDM module in the drivers door?????
Secondly, the CTS switches are most likely not compatible with the AV or EXT... does not an easy option......

Chris, first to correct my above statement, (I actually went back and looked at my post... see below) I did say that the '02 EXT did have express down on all four according to the Canadian GM website.

Mate I'm sure you're right about the '02 switches not likely to work in the '03's I'm saying that based on my guess that Cadillac went for the class 2 wiring in '03 just like Chevy did... although, maybe they went earlier?? Just a guess.

I recall making the post below as part of the research into the RH conversion I needed to get done... my thought was that a Canadian member might swing into a dealership next time they drove by and actually give us the answer to my question... never did get a response though and now of course the info on the website has changed and I can't even prove to y'all that I wasn't imagining things. DOH!!

I wish that jeremyloomis58 would respond back into this thread, he sounds like he's got some real knowledge in this area.

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) :D could confirm or refute the above information.

Cheers,

Skidd 7;)

I was not trying to imply that you were wrong ( for 02 )...
I was trying to say how easy it is to forget the differences between 02 and 03... A lot of behind the scene changes occurred between the 02 and 03.. had to believe that would happen to a new vehicle, but you have to remember that the GMT 800 initiated a mid lift change.. Started with the IP having dual climate control and rapidly progressed from there... yet hard to see at first glance.....
Time to get out of work and go home!!!!!


dichris
 
Yeah... the main problem is that we (I) just do not know enough about the class 2 system and if the various modules (DDM & PDM) are reprogrammable or how to get these things doing what we want rather than what GM intended.

I asked this question around work and have been told by several people to talk to this one individual... Every time I go to his office, he's in a meeting somewhere else or he's in a private closed door meeting in his office.... Or my on one of the other 2 shifts.... Eventually I will be able to bug this guy for some info, and hopefully he will be able to provide me with useful info for us @home type of players.... Hopefully he knows of a product other than the Tech II to reprogram....
When I find out, I will advise...

Now that would be great!!

I'll give you some background on why I want to know..

For the right hand conversion we had to move the main window switch block onto the RH door so it can be worked by the driver. I was thinking that because the switch is not reversed that it should work fine.... but no mine has the switches working opposite.... hard to imagine I know;

Picture the driver is now in the RH seat, I want to put down my window (drivers) it is now the RH window, but after the conversion the front LH switch works the front RH window. I'm guessing that it is because we have moved the switch module but not the motor there is some confusion (or not) in the electrics. I'm guessing that the motor has a class 2 address associated with it and no matter what I do unless I reprogram the switch and motors I will have to live with all my switches being backwards.

It's interesting 'cos they all are even the mirror selector switch. The converter can fix it by altering the printed circuit board in the switch... but I will only do that as a last resort.

So if we can find someone who really knows what makes these things tick, I'd be very grateful. I have access to a Tech II so that woldn't be an issue for me. :)

Jeremy,

I was hoping you would come back into this thread... If you read my post above on how the RH conversion I have done has effected the window controls.

I would be *VERY* interested on how to reprogram the window switches so that they work correctly. If this is sensitive GM type stuff that cannot be posted on here then please PM or email me as I really would like a hand to solve the problem.
 
I have a 2003 silverado, the interior on the 2003 AV is the same. We have a daughter that always will be riding in the back. If I turn on the child lock feature that keeps her from opening/closing the windows, it also activates the front passenger side switch. Is there a way to allow the front two to work regardless of the position of the child lock feature? My wife gets mad when she can't roll down the window on her own.

Thanks,
Scot
PS Please email me @ smckitt@verizon.net as I don't check this often. Thanks.

I get this all the time too.,.,...I am not sure of a work around excpet for maybe a BCM reprogram....

I asked this question a couple of months ago and we never found a way to do it on the 2003+ models. If memory serves, someone did post a fix for the 2002....
 
I was hoping maybe I could take the switch panel off & make a few small rewiring connections to bypass this child lock switch for the front passenger side.

Hmmmmm......?

I'll let you know if I find anything out.

Thanks,
Scot
 
old post iknow, but i take it noone has figured out the 4 way auto up/down
controls? if not... i vote its still in need of some investigation!!!

i'll start pokin round at my buddies shop, were pretty good at "rigging" things
