I'm having an issue with my 2020 Equinox, most would think that it's a common shift-to-park issue, but I'm not so sure, as I've checked and replaced a few things.
I opened the shifter and checked the switches. They worked, but i already had bought another shifter assembly, and the error has not gone away.
I noticed that the e-brake does not light up or function either. LED on shifter **** doesn't light up. The F21 shift controller 20A fuse is working. Physically moving the cable along the different points also changes nothing, staying in "N". Also tested the F06 TCM 20A fuse.
Does anyone have a wiring diagram of the fuse boxes as well as the route between the shifter, TCM and BCM?
Car won't start. Manually pulling the cable I can move it into neutral and roll the car, so I know that the transmission isn't sticking. I thought a relay or fuse because of the lights being out on the shifter **** and e-brake button. Lights are on the shift indicator. Pressing the brake, the brake lights come on, but there is no "click" from the shifter that would indicate the shift lock has been released. There is 11.5V going into two of the three power wires to the shifter.

Any help would be appreciated, I'm new on here. Usually solve things on my own, but this has me stumped.
