If the brake lights works, no need to replace the switch. This is due to the interlock solenoid not working and not releasing the locking tab for you to shift out of park. The brake switch is part of it and since it is working, we would need to check others.
Check the fuses first.
Which engine do you have?
Is the P indicator light showing correctly when ignition switch is turned on?
I could not find any reference to the interlock system in our database and there is a possibility of it being mechanical.
