to add, BVVU,
The brake light switch, if I'm correct is just up from the pedal. If you run your finger up the shaft (huh, huh, shaft) from the break pedal, you'll come across a little 'T' that presses two little buttons in, I imagine one is for your brake lights and the other is the safety switch that keeps the shifter from being put in gear without the brake on.. you could try tooling with those buttons and it might click something to where it should be...
and by tooling, I mean pushing on the buttons... any further than that, just take it to the dealership.
