Piston Slap: The Body Control Module Electric?

Good Afternoon,

Today when I got into my 2002 Saturn SL2, the power door locks started chattering. Each door, over the space of about 45 minutes, had the same thing happen. Sometimes it would be one at a time, other times it would be two or more. I also noticed that the inside locks – the “up/down” button, not the little lever you use to manually unlock the car – would not work, only later to work. For now I have removed the lock fuse and that stopped the problem. I wait and plug the fuse back in, and the sporadic chattering once again begins. Sometimes it is completely quiet. Any thoughts?

Thank you!
