Body Control Module Problems after Dash Removal(Pics and Questions)
I was doing my 4th Dash Removal and first one for a LS1 all the others were LT1, not that I thought it would matter. After doing it for HVAC removal on a 99 Camaro we reassembled the the dash and noticed the windows would not roll up. When the Key was foward if you hit the lock button to "Lock" the Courtesy bell would start ringing faster, you turn the key off, the locks work fine. Either way windows wouldnt work. Everything was checked and doubled checked, nothing was cut and I had never had this problem before. I posted earlier and someone said it might be the BCM, so I have a 97 that we borrowed if from. We plugged it in and the windows and door locks work fine, but the car wouldnt start, most likely I am assuming this is from the VAT Key System.
I searched and am curious can any other thing cause this are they that sensitve internals?? Is our only choice to buy a new BCM off ebay or GMPartsDirect?
On a Side note does the BCM also control the radio power and such?
Here are a few pics that I am curious to what they are.
What module or control is this? Below
Double Plug in: What is this one?Below
Here is 2 relays black and gray, I believe the gray controls the alarm
This has some type of Phone RJ Connection on it, what is that used for?
Any help appreciated.

4719 looks like the express down relay for the windows.
4720 not sure yet
4721 in hand looks to be the theft deterrent relay and the other the hatch release relay (they are usually together by the glove box).
The BCM has the VATS in it, so if you swap it out, they key pellet must match. What happened to the original BCM?
The BCM will also control the retained and accessory power for the radio, windows and such (which some of you already found out).
4722 don't know.
