Body Control Module Issues BCM
Over the years we have had continued issues with the Body Control Module located in the passengers footing area. We are now on our 3rd replacement. The replacements have all been remanufactured to include one we just had replaced at the Dealer. A new BCM was not available. I wanted a new one and not rebuilt after 2 rebuilt or remanufactured ones failed. The 2 remanufactured ones were replaced at a non-dealer repair place. They would last a little over a year or so. One was replaced under parts warranty. The dealer had to send my remanufactured BCM that had failed to have rebuilt again here in Tampa. Apparently, there is a place that rebuilds for GM right here in Tampa. The dealer stated there were no signs of water damage or other issues causing the BCMs to fail. The dealer found no shorts or other issues. Of course, hopefully, the Dealer Technicians did a good job diagnosing the issue. I have a year's warranty on this one from the dealer. We purchase our Vette new and intend on keeping it.

What has the reason been for replacement? Any specific codes you remember? Who did the replacements?
My buddy has a 2000 that the BCM got wet in and had starting issues. I opened it up and found corrosion around 2 relays at the edge of the board. Unsoldered them and cleaned the board the reinstalled the relays. Put it back in the car and it has been good for the last 10 years.
Have seen a couple of other cars that seemed to have the same issue with out a sign of water in the area of the BCM. Did the same with these, cleaned the light corrosion off the board and it worked again.

So far so good with my newly remanufactured BCM. We have driven the Vette several times with no issues. Hopefully, this BCM will last. As this is a convertible will make certain left in our garage overnight although they did not find any moisture-related issues.

But I do remember the GM had the circuit diagrams printed to get the literary copyright protections unavailable to car parts. So don't expect much aftermarket help without a change in GM parts philosophy

IDK if the following is true, or not. A reputable shop told me this, so they should know. Anyway, here goes: To avoid any electronics damage in the C5, I've been told that you shouldn't ever disconnect the battery with the key in the on position, and they further stated it shouldn't even be disconnected with the key in the ignition, regardless of position. FWIW......
