5901 on 04 armada doorlocks stopped

Hey guys, I installed a 5901 in my Armada a few months ago and recently my door lock functions have stopped working (they have worked fine until now). Arming, disarming will not lock, unlock. Ignition lock/unlock does not work. I can hear the relays doing their thing, but the locks do nothing. When I installed it I tied into the wires in the doors (the same wires coming off the door lock button which still works). I pulled the car battery to reset everything, no change. Any ideas what else I can check?

Check for broken wires thru the jamb boot first. Second test for output at the 5901 and trace from there...Mike M2
