Body Control Module
What exactly is the Body Control Module? Where is it located and how much do they cost to replace. I'm starting to have funny electrical problems with my car and I was told that it may be the BCM. If its cheap I'm probably just going to replace it? Any info would be greatly appreciated.

I'd like to know that aswell

Are these capable of controlling female bodies as well :confused:? Because that could be very useful :D.

i believe it is located on the front right of the passenger footwell. Just remove the kickpanel and it will be directly behind it. I think it only controls the keyless entry/power door locks.

Excellent youtube 15-minute video on where to find the Body Control Module in a 1999 Z28, how to remove it, and how to re-solder the pc board connections:

Not too bad a video, but I have some "suggestions"
See my procedure here: http://www.firebirdnation.com/forums...al-and-repair/ 1. I highly recommend removing the glove box first. It only involves removing the 3 screws and will leave you with much more room to work. I did not have to remove the seat. 2. Please don't pull on the wire antenna inside the BCM case to lift/pull the circuit board. It isn't necessary and you may break it's solder joints too. 3. His bad solder connection was simply broken, not "cold". The relay on top receives a lot of abuse when the BCM is installed into the cramped holder or when the blower motor (very close by) is replaced. That transfers force to the solder joint on the bottom. 4. To repair the circuit board, all you need is the soldering iron and maybe a little bit of rosin-core solder. You don't need to remove the old solder and clean the board. You just "reflow" the existing solder using the iron and perhaps adding a small amount of new solder at the same time. Takes about a minute at the longest. This is the way it is done in manufacturing factory rework. 5. If you do want to clean the circuit board, use only 100% alcohol (not 91% or other). You don't want to leave any water deposits. All the above from an electrical engineer (me) with 45 years experience in the field. |
Re: Body Control Module
anyone know where to get a replacement for a decent price?
I can soder but not real percise with it |
Re: Body Control Module
All you need to do is re-flow (melt and let cool) the existing solder really. It's very easy and takes about a minute or less.
If you replace the BCM, you will probably (14 chances in 15) have to get new ignition keys to match the VATS resistor value already programmed into the replacement BCM. |
