can't get it out of park!

For the past four months we've been having trouble getting our 05 Saturn Relay out of park. It doesn't do it all the time. Seems like if we let it warm up it goes into drive fine. They've replaced a brake switch but it still does it. Any ideas? Thanks!

The brake switch probably operates a relay, to 'unlock' the shift mechanism - and I would suspect that relay is not working. If the relay is in the bottom of the console, it could have gotten something spilled there, like a soft drink, that is gumming up the 'unlock' mechanim. This is my wild guess, since I dont own a relay; and have defeated the brake-shift interlock on a couple of our families cars.
