Checking to make sure your BCM wiring harness is not chafing:
If one removes the glove box, the BCM is visible behind and up to the left under the dash. Behind the glove box once it's removed you will see a metal bracket that runs parallel to the dash with a notch cut out on the right side.
The cable that runs to the BCM runs vertically (which is hidden behind the glove box but visible one its removed) to it but as many have reported I was told, the wiring harness rests against the bracket at that notched cut out. From vibration and over time it chafes against the metal causing the casing to wear through exposing bare wires, some have reported BCM issues and this was found the chafing to be the culprit. A few in our club took their glove box apart and found their wires were chafing as well. My BCM was changed years ago and the new one installed the wires were not in contact.
The fix: Some have added rubber tubing to help insulate it. Although I had no issue and since my glove box was removed, I wire tied the harness to: If you look over at the fender from inside the glove box area there is a round bracket or brace that runs vertical in front of the fender. I wire tied the harness to that bracket just as a precaution. This allows ample room between the wiring harness and that bracket.
To remove the glove box: With the glove box open, look to the left side wall of the interior you will notice a rubber plug about about 1-1/2" long. Carefully pry this off while holding the glove box. There is an identical plug on the right hand side, leave that one alone. Once the plug is removed the glove box will open downward, twist it gently upwards to the right, the glove box will release from a plastic stud sticking out of the dash on the Left hand side. Remove the glove box. To reinstall reverse the order making sure you properly seat that plug, it may take a couple of tries as it must snap all the way in or it will be misaligned.
