'02 Corvette Door Lock

Door lock on the passenger side will lock, but not unlock from the driver door, passenger door, or the FOB. Any suggestions?

Thanks.

I have a 2000 that has had a similar issue only with the passesnger door. the door will unlock, but will not lock via the remote or the power lock button on the driver side. What did you end up doing?? the dealer want $135 just to look at it as a standard fee in a south florida dealer.
