BCM Question
Has anyone of you had to replace the Body Control Module on your C-5. I believe I may be having to do that soon. Can you tell me the kinds of things that happen when one goes bad? On my 2001 coupe, I get all kinds of warning messages on the DIC and all the lights come on, such as the Active Handling Light, ABS light, etc. I also get messages like, service engine soon; reduced power; check tire monitoring sensors; low fuel; etc.
Also, my windows quit operating; as well as the power door locks and the radio quits working.
I can turn off the engine, and it may clear everything and then act like nothing is going on for a day or two, and then the same things happen again.
I have replaced the battery and had all of the 9 grounding connectors checked and tightened on the car. My mechanic, who is not a dealership, advises me to take it to the dealership as he says the BCM is warranted for up to 8 years.
Does anyone have any expertise in this area? Your help is appreciated.

Ebay has them all the time for cheap money, I had to replace mine in my 99 Z28. The horn would beep all on it own for no reason. Got mine for $35 on ebay and it worked until the day I sold the car.
