Default power door locks wont work

have a 2001 gmc jimmy and while driving down hiway i heard all my door locks pop up.when i went to lock them again nothing worked.Tryed using the key fob as well as the drivers door master powwer lock but got no response from either.checked 3 amp fuse under the hood.it was fine but changed it anyways.still nothing.Poer mirrors still work but only way to lock doors is to manually push down each one individually which means i cant lock my hatch.something is also drawing power when the vehicle is shut of because when i leave it overnight the battery gets run down..also,after locking the doors if i walk up to drivers door and pull up on the handle on the outside i can hear the drivers door lock pop back up unlocking the door without putting the key in door lock or anything.Does anyone have any ideas on what this could be?thanks for any help

Start with the simple and disconnect your power door lock switch one by one. Start with the drivers door lock switch, once you have that switch disconnected.

Try to lock your doors with the fob keys, if it works fine and your battery does not drain over night. Then replace the switch or try cleaning it with electrical contact cleaner.

Good luck and keep us posted.
