Default power door locks dont work on 90 lx sedan

90 lx sedan, everything else works just not the power door locks. The relay box just clicks when the lock button is pushed. I don't see any visual damage to the wiring, will check w dmm and test light for continuity. Trying to install an alarm and would like to use the stock locks instead of running more wires for actuators. Any ideas what could be wrong? I have. A pdf of hondas helms manuals if it helps

If you can hear it clicking, sworn is likely fine.
Probably bad ground

Like bad ground to the modual in the door ya? Because none of the doors unlock or lock electronicly, the modual is what sends the +/- signal to each door lock actuator right?

Yes. A poor ground at the control unit would cause all locks to be inoperative
