Problem was 2 years ago, but here's an answer for anyone with similar probs. Replace your brake switch (near the top of your brake pedal arm. This switch controls not only the brake lights but the lock-out function of your shift lever (automatic trans.) If it's not working, both will be non-functional - as well as cruise control. First, check to see if you have rear brake lights when stepping on brake. If you do not, and also don't have shift-from-Park ability it's most likely the brake switch. It's a $10. part on the web, more like $27. from a dealer, and can be installed yourself IF (and it's a BIG "if"!) you can tolerate laying head-down on your back under the brake pedal and looking up into (and working in) a VERY confined and tight space. Claustraphobics will NOT be happy, guaranteed. Otherwise, just disconnect the wiring lead from the back of the switch, turn the switch 1/8 of a turn (see link below) to release, remove it, replace with new switch, turn to lock in place, replace wiring lead - voila! If you're lucky, it's a 2 minute repair. If your arms won't fit in well or you have claustrophobia or a bad light source - well, good luck. Just make sure switch is seated properly after re-install before reattaching lead wire - no wobbles and good tight fit, or you'll have to pull it again and re-seat it.

Good luck!

That would be called the shift interlock feature. It operates on the same circuit as the brake lights so the first thing you want to do is to make sure the brake lights are working when this problem is present. If the brake lights are working, that proves the circuit is good up to that point, then you'll have to get to the solenoid in the console. Disassemble as much as you have to to access the solenoid near the shifting mechanism. Us a 12v test light to test for power coming and going at the solenoid when the brake is applied. If power is arriving and switching and the solenoid is not triggering, the solenoid is bad and will have to be replaced.
