Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
Do the brake lights come on when you step on the pedal?
Can you hear a slight click inside the shifter housing when you step on the brake with the KEY ON?
yes, we have brake lights
however there is no click with key on when brake is depressed
You will want to check the #42 fuse in the under hood fuse center, (NSBU)
If that fuse is good, then there may be some gummy debris down in the shifter housing.
Yes, there is a little rod that has to pop in to be able to get it out of park. Sometimes the actuator might be good, but the rod gets a little gummed up in there. Here is where it is.
would something like chemtool rinse the debri out? by applying around the shift button it self or is it lower down the shifter.
