93 Nissan Pathfinder Power Locks DOA!?

[rrack]

I've got a 1993 Nissan Pathfinder with the factory door locks that are operated by the factory alarm system. Recently the power locks completely stopped working. The alarm still seems to work just no power locks. I've tried checking the fuses in the dash kick pannel but there isn't one labled for the locks. Is it hidden in another place? I can hear a relay click in the left rear side pannel when I press the lock/unlock door button but that's it. The cheapo Haynes manual doesn't tell me anything.

Thanks, Robert

Check the lock actuators. I had one where the passenger door lock actuator was frozen and would cause all four doors to unlock all the time. If one actuator fails the whole system may not respond the way it should.
