2001 Mustang is stuck in park. Cannot get out of park when I push the brake pedal.
See if the brake lights are working.
Also, as a work-around, try with the key in the ACC position, where the radio is working, but no lights on the dash and the engine on running. Shift to neutral if you can.
Brake lights not working. Found wire broke under brake pedal. Connected wire, problem solved. Thanks for your help.
