Please tell us more about the situation. Is it locked and you can't unlock it? Is it jammed? Is the release moving but doesn't seem to be connected to the machanism? Probably you'll have to get inside the rear compartment and remove the interior trim to get at the mechanism.
Here's a directory link for you:
