1997 Honda Civic LX 4dr
The power door locks on my car are not locking/unlocking the doors. None of the doors. I checked the fuses and they are ok. I also tested the switch and it showed continuity for both lock/unlock. I then reconnected the wires and tested them at the other end, where it plugs in to the Power Lock Control module and flipped the switch again. Continuity appeared on the wires there. That eliminated a bad wire from the switch to the module.
I then, referencing the wiring diagram in the Haynes manual, tested continuity from the control module to the driver's door lock actuator. This seemed strange to me, but the wires which were supposed to (if I read the diagram correctly) indicate the switch locking/unlocking showed continuity without doing anything to the switch.
With everything plugged in, toggling the switch does not result in any sound being made (the typical clicking sound that occurred when i would lock or unlock the doors)
My questions are:
1) how often does the power lock control module fail?
2) how can i remove the actuator to more easily test it?
3) does the lack of that sound indicate actuator or this control module?
4) would a failing driver's door actuator cause the other doors to not lock/unlock, or are most likely all 4 door hosed up?
Let me know if you need anymore info or more explanation. I'm also attaching a pic of the control module from one i found on eBay.
