2007 Tahoe Power Locks-LH Only not working

Sunday I hit the locks on the fob and they all locked except the drivers door. So I assumed the actuator was bad. Today I put in an actuator and still nothing. All locks work with the fob except drivers door. No dome light with drivers door. Radio still plays when door opens until it times out. So now I am afraid it is the DDM. It did get a little wet on Saturday. They are pricey! If you buy a used one does it have to be programmed or just new ones? No locks work with the master switch on drivers door. I didn't try the windows, but I will later. Any thoughts on diagnostics? Thanks!
