The brake lights on and the manual shifter doesn't work, and it's stuck in second gear.

Hi,

The shift interlock which prevents the shifter from moving is powered by the brake light switch.

I attached a pic below showing a fuse to check. In addition to checking the fuse, make sure there is power to and from it. Here is a link you may find helpful.

If the fuse is good, I need you to locate the brake light switch at the top of the brake pedal under the dash. Identify the pink wire with a dark blue tracer. Check to see if there is 12v power to it. If there is, back probe the dark green wire with a white tracer and confirm there is power out with the brake pedal depressed.

If there is power in and none out, replace the brake light switch.

Let me know what you find

Take care,
Joe

See pic below. Pic 2 shows the fuse location in the under-hood fuse box.
