If anyone has any info on how to fix this I'd be very appreciative:

Nissan 240sx Single wire system ( ground to unlock)

Brand new relay that I'm sure is working

The power door locks will not unlock when the alarm is disarmed nor will they unlock in response to channel two, tried going through the setup again, no luck. But The doors WILL lock 3 seconds after the ignition is turned on, just like they're supposed to . So, I know that the alarm cp can at least send the lock pulse to the relay, but the unlock just doesnt seem to work, as far as i can tell the alarms ground is good, what else can i check?

Does the module at least "click" when you try to unlock it?

Can you probe the unlock wire, and see if it shows ground when you unlock it?

Just a couple things to narrow down what could be broken.

If you check the Nissan one wire lock relay design on this websight it show that you how to wire this right with two relays , and if you are using two , that will show you what all the wire values need to be so you can check them all with your DMM .
