Back passenger side lock does not work - help

[NJaloha]

Ok, the lock itself goes up and down when you do it manually. However when you do it via the control on the driver's door, the lock does not respond, only a funny clicking sound. Any ideas?

I'm having this exact same problem with my drivers side door and my rear passenger door. I'm really hoping somebody on here knows how to fix this.

Hey rusty nuts, do your doors also make this funny clicking sound? Something is not engaging and I'm not sure what or how easy/difficult it is to fix. My car has what appears to be the common P5 problems: rust, seatbelt buckle and now this.

It's the door lock actuators. There's a plastic gear inside the actuator that breaks. Unfortunately, you have to replace the entire actuator, but fortunately not the whole lock assembly. It's not too difficult to do. Mostly irritating more than anything. Onlinemazdaparts.com has them around $40 each.

There's a guy from Australia selling a replacement of that plastic worm gear/cog that has broken and causes that rattling noise. The title of the current auction on ebay is:
