how do i replace switch lock sensor in my 97 geo prism

When the inop brake lights are fixed .. The shifter problem will be fixed as well...!

I checked fuses all are good and i replaced brake light switch. Still wont release. now i did find an article thru geo forum that if i can manually get the shifter to shift it stated that if i can manually release shifter that switch is bad. It said that if it was workin correctly i shouldnt be able to move it out if park.

1 question - Do the brake lights come on when a helper pushes the brake pedal down?
