03 escalade ac not working. While inspecting I noticed a random cable unplugged and i can't seem to find where it goes. Would this affect the a/c?

That is for the extra battery setup which is part of the police package(you can get the add on at a Chevy dealer if you wanted to add a second battery)

Gm pre wired these trucks for stuff they didn't get for civilian duty that way if they was used for fleet use(eg police duty) the harnesses would already be in place and ready for the up fitters to use when they added on the extras needed for fleet usage

You can hear the ac compressor kick for sure(I know I can hear mine when it's engaged on my truck)

Not sure on the part number for the second battery package add on

I am sure it's part of the second battery package add-on(can verify with my local dealer next time I go to be 100% sure)
