Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
You dont mention symptoms, nor mention how you are confirming the bcm is faulty, nor whether you are replacing with a new, remanufactured, or junkyard bcm
I can only give an answer as accurate as you provide details. the less details, the less accurate the answer may be. So if you would like to provide more details, I can give a more accurate answer
With the total lack of details given, it could be you are using junkyard parts, have short in the power feed wires to the bcm, or possibly backfeed from one the many electrical accessories it controls
