Default door locks not working

The other day my windows stopped working, wouldn't move at all. Thankfully the windows were rolled up so there was no issue of security or inclement weather. I pulled the door panel off and there was power to the switch. After messing around with the wires, the windows started working again; I'm assuming bad ground or loose harness. Before I put the door panel back on, I tested all the switches to insure functionality, and low and behold, the door locks stopped working. They will unlock from door switch and key fob, but will not lock from either the switch nor the fob. There is no sound when hitting the lock button either. Providing a ground to the the unlock wire will activate the unlock motor, but nothing happens when a ground is provided to the lock wire. Any idea what could be causing the issue? The horn does activate and security system arms when I double click the lock button on the key fob.

Sounds like a bad relay if grounding the switches worked.
