Changing BCM so it will suit power windows
Ok Guys none of the threads i read make sence or my question is just different to the others.
I have a VS acclaim that i wanted to put power windows into. I have checked my BCM and it is a low one. The other BCM i have is a LUX one assuming Lux is for Luxury it is out of a VS Berlina. I have all the plugs and wires already in my car as it is an acclaim so all it should be is plug and play so to speak.
I have tried one side and everthing plugs in but windows dont go up or down with my low BCM. My question is if i put the LUX BCM in will my key work? Do i need to change my ignition barrel central locking to suit the LUX BCM?
What is the best way to go about this?
Any answers would be apprichated.
Thanks

Your key will be fine, you will need to change key heads though, so if you get a new bcm you will need the keyhead that comes with it.

You only need to have a matching Key head for the BCM. Then swap the key blade into the new key head, But you might find the plugs are different on the BCM.
Yeah thats sweet as i have the key head for the other bcm. What about the central locking?Originally Posted by edals
I have the key head to the other BCM my worry is the central locking or will it just adapt to the other bcm?
Just read the last bit properly holden made the end plugs different?
The key head is match to the BCM so if you swap the BCM over with the matching keyhead, the immobiliser and central locking should work fine.
Did your acclaim have the fuse installed for the power window (fuse slot 5 I think) along with the half relay?
Does the power window control panel light up?
The low series (apart from the ute bcm) BCM should work with the power windows although you will possibly need to bypass the BCM as the low BCM does not support the auto window down.
If you've installed the rest of the power windows, does the passenger side work?
Also lux BCM probably won't plug up into your existing harness as it has a couple of extra plugs for the bcm and features.
Electric windows and fuses
My acclaim had all wiring but no fuses I had the fuses from my Vs wreck. I am going to check the lux bcm before I put it in. I am not going to pull the other doors apart until i no it is going to work. Did the drivers side and it didn't work so I assumed it was to do with the low bcm. Panel lights up very nice

Real cars are steel cars.
The Acclaim is fitted with a LOW BCM without power windows and a MID BCM if it is. The plugs for both are the same.
The LUX and HI BCMs all support power windows but the plugs (two extra on upper levels) are different to the LOW/MID BCMs.
Apart from a matching key head, you will need to fit (or adapt) the Berlina/Calais loom to connect to the LUX/HI BCM.
They also have different headlamp switches (dimmer control & timer for headlamp control), rear demist switch (timer function) plus some other functions I cant remember.
To go from LOW/MID to LUX/HI is not plug and play.
If I told you I was a compulsive liar, would you believe me?
I used a vp window module retained my original low bcm and didnt have to change any keyheads and still didnt interfere with the cars wiring too much and it works a treat with auto down and window power off timer

Great idea!!!

So it appears dont use the LUX BCM unless your changing over the body harness on the right hand side.
If you have it on the drivers side, a couple of things to test. Just press up on the window switch and you should hear and see the motor try to put the window up and then stop for a split second. This will confirm that the motor and switch work. Pressing down wont work on the LOW BCM as it doesnt have the auto down feature supported.
If that doesnt work, hook up positive and negative power to the end of the power window motor and it will go down or up depending on which way you've got it wired.
The rest of the doors should just plug in and work as they do not have the auto down.
To get the drivers window to work you need to by pass the bcm, so feed power from the switch direct to the regulator motor. If your going down this track let me know and I'll find which colour wires you need to join
Or you could use the VP module or get hold of a MID series BCM.
Great info from all you guys. Will have think of which way I am going to go.
Anyone have a mid bcm and key head I will swap for a lux and key head.

Just remember it must be from a VS. (VR BCM wont work in a VS)
If I told you I was a compulsive liar, would you believe me?
thats weird it didnt work,i put power windows in my old vr acclaim and they went straight in,didnt have to touch the bcm... i wonder why the vs would be different,especially if you have the wiring in there already?
I imagine the wiring is there and if they want power windows they just swap the low bcm over to a
Mid one for it all to work properly.
This is what i think they do. Anything to get extra cash.
You got lucky yours must have been a mid BCM.
maybe someone swaped yours at some point?
Maybe but if you had electric windows you wouldn't take them out.
i meant that maybe at some point,someone lost the original keys or something so they got another bcm and key second hand but got a low one instead of a mid bcm...
From what Ive read on here,especially from guys who post about fitting central locking and power windows to their VS series 1 utes is that if the wiring is already there,the BCM will support the power windows(and central locking).If a BCM that doesnt support power windows is fitted like in the series 1 VS ute,the terminals in the fuse holder and relay holder are not there.I have a VS exec with a low 150 type BCM.I dont have power windows,but have the wiring connectors,the fuse and the relay terminals there all ready to go..As far as I can work out,all I need is the power window mechanisms,the switches and door wiring looms to have power windows.I could be totally wrong about all this though,Ive tried for ages to find someone who has the original factory power window option fitted on an executive VS to see what BCM is used,and I havent found one yet to look at.You would think someone would have ticked the power window option box when buying an executive VS.

I have a VS Acclaim with a low BCM and no power windows, all factory standard.
A very good mate has a VS Acclaim with a mid BCM and power winddows, all factory standard.
I believe all VS Commodore/Acclaim had the window looms fitted.
If you look in the VS Workshop manual it lists the part numbers and functions af all BCMs.
