CHECK TO SEE IF YOU HAVE BRAKE LIGHTS. YOUR VEHICLE USES A SYSTEM THAT WILL NOT ALLOW IT TO COME OUT OF PARK UNLESS YOU HAVE YOUR FOOT ON THE BRAKE PEDAL ANDYOUR VEHICLE NEEDS TO SEE A BRAKE LIGHT SIGNAL FROM THE BRAKE LIGHT SWITCH TO RELEASE THE SAFETY SYSTEM. YOU MAY HAVE A BLOWN FUSE OR SOME OTHER FAULT IN THAT SYSTEM. HOPE THIS HELPS! GREG
I had the same problem with my '98 Grad Am. There are two switches (buttons) that get pressed when your foot is OFF the brake pedal. The lower one turn off the brake light and lets your cruise operate. So when you press the brake pedal, and move the pedal off of the switch, the brake lights come on and the cruise gets turned off. The upper switch or button, seems to operate some kind of lock mechanism on the shift lever, so when you push the brake pedal all the way down, it comes off of this upper switch, and releases the mechanism, allowing you to shift out of Park. I have not been able to replace this switch, but I did remove it, and my problem was solved. The only problem is that I have removed this safety interlock, so now I could actually shift out of Park without the brake pedal pressed.
