Automatic door locks not working properly.

wvgirl1

have a 2005 chevy Malibu classic 4 cylinder that the automatic door locks are not working and the horn beeps intermittently. Feel it is a relay switch or fuse. What do I need to replace and how much would it be? part number? This just started in the past two weeks. Fund our battery was bad so we replaced it but the door locks problem are still there. So I am assuming it is a switch or fuse.

Are you using a fob to open/close the doors? You might check its battery, or just change it out. If that's ok, might be the control module in the driver's door. A computer scan might turn up something.
