Hello my name is XXXXX XXXXX X will be more than happy to assist you.
Your problem can be the BCM, but it also can be wire related. When driving can you lock and unlock the doors from the passenger door and also with the remove?
There are a few test I can guide you though to see if the body control module is bad or if you have a wire issue.
If you have a Test Light or Volt Meter with a Ohm setting let me know and I will tell you what to test.
Here are the instructions to get to the body control module.
Unplug the body control module, hook the test light to battery positive, and touch the test light to each of these slots for the body control module connector
Blue connector Slot D11 Tan Wire, D12 Purple wire, and D13 Orange wire
Does the test light light up? Make sure you do the test with the doors closed.
The except only shows when I hit the answer button. Since we are still trying to diagnose the problem I have no answer at this point.
Thank you for the Accept and Bonus.
Let me know what you find out tomorrow so it know if you problem is the BCM or Wire problem.
This is the only diagram gm has for the AMP.
Labor time is between 1.8 to 2.1 hours
Some of the instructions are missing for some reason. The hole console comes out.
