Key is stuck in the switch, will not turn to off. Won't go to "off" from accessory, almost as if there is something jamming the switch. Everything operates as it should, the vehicle will start and shut down. Unlike the earlier years, there doesn't appear to be an interlock relief accessible from the holes under the column.

Welcome to 2CarPros.

I need you to check a specific fuse for me. It is the BCM 2 fuse. It will be located in the under hood fuse box. See picture 1.

Here are a few links you may or may not need. I'm adding them to help if needed.

Also, I attached a picture (picture 2) that shows the BCM2 fuse along with two ignition fuses. Basically, it is a picture of the under hood fuse box. Please check the ignition fuses as well.

Let me know.

I have electrical skills and tools.
The vehicle is charging at 14 volts and the resting voltage is 12.8 volts.

With the ign sw on [off] position l have power and good fuses at the 2A IGN SW and the 15A BCM 2, and no power applied to the 15A ECM/TCM fuse.

Turning the switch to the [on] position give power to the 15A ECM/TCM fuse, which is good.

While I was there I checked the rest of the fuses, if they were powered they checked good.

The transmission gear indicator shows '"park".
How do I access the cylinder lock solenoid?
Is it powered or grounded by the transmission?
Is there an online wiring diagram out there? I came up empty on my search.
