Oldsmobile power locks not working

Hi. Oldmobile Cutlass Supreme wit 166k miles. My power lock does not work. Neither the keyless remote or the buttons on the forward doors close them, but the switch and the remote are able to unlock them all. One press, unlocks the driver's door. Press twice and all unlock. Any press in the switch make them unlock. But locking is only possible by moving the locking handle (4 doors) or using the door key on the front doors and manually in the rear ones.
Any suggestion?
Also, I can hear a little click when activating the switch for the lock all position, coming from behind the glove box, but cannot locate the relay or fuse it comes from.

Thanks for your help.

Sounds like you have some door lock actuator failures there, and yes it could be all four, you can do a preliminary check by sitting in the vehicle where it is quiet and hit the door lock in the position it wont move by using the master door lock switch and listen by the door panel to see if you can hear the actuator try and move, if so it is faulty and check all the same way
