commando power locks

I just installed commando power door locks on my 2-door nissan pickup.  It's supposed to be a central locking system (lock/unlock one door, the other automatically locks/unlocks) and it works fine when locking, but when I unlock one door, the other door does nothing.  They both lock/unlock when I send a negative impulse to the extra wires that are supposed to go to an alarm.  Anybody know what I can do to fix this?  Thanks

Thanks, but I tried that........I even tried working the locks with the rod completely disconnected...........don't know what the problem is.

BTW, I'm assuming all 5 wires going to the driver's actuator are connected. the12volt • Support the12volt.com

If all five wires are connected and the door locks only respond in one direction, it sounds like you have a bad actuator in the driver's door.  the12volt • Support the12volt.com

Well, if that were the case, shouldn't it still work for unlocking when i unlock the passenger side, since they both have 5 wires?

I see, only works from either when you lock and not unlock , and works fine in both directions when you use a negative trigger. I'd take the cover off the relays if possible and look for a bad connection going to the coil of the unlock relay coming from the main harness that connects to both actuators. Sounds like that's where the problem is.  the12volt • Support the12volt.com

ok, thanks, i'll check into that!

ok, here's the deal............i took the cover off the module and on the back of the green board there's a flat piece of copper that's, for some reason, come apart and it leads to the pin that plugs into the unlock wire........now my question is, how do i fix it?  seems like soldering is my only option..........any suggestions?

Koo, you found it. No suggestions, just solder. the12volt • Support the12volt.com
