Power locks don't work from Driver side panel

Hi,

I just bought a 2005 Cobalt for my daughter and the power locks don't work from the driver side panel. They do work from the passenger side panel and from the remote keyless entry. Any suggestions on what might be wrong here? I planned on opening it up and taking a look for a fuse this weekend.

Thanks

It's probably just a bad switch on the drivers door, because of wear, tear, and drive up windows at local fast food.
