Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

The radio still does not work and the A/C pump, won't start, turn signals don't click when using and leaving the key in and opening the door makes no sound.

You need to check the RDO and AMP fuses, but it sounds like to me that the BCM is out, to be sure, let's do a CAN scan. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Here are the radio and amplifier wiring diagrams so you can see how the system works. Also, I have included how to swap out the BCM for a preprogrammed unit for easy installation. Check out the images (below). Please let us know what happens.
