457g crazy locks/unlocks

I've got an 04 Trailblazer, Clifford 10.5x Matrix, and DEI 561T. The 457G has done everything great including the remote start but screws up on the door locks/unlocks. 457G: If I touch the blue (unlock) wire to the chassis the car will unlock. If I touch the green (lock) wire to the chassis the car will do nothing. If I touched the blue (unlock) and green (lock) wires together the car would unlock, until now. Clifford Matrix 10.5: I didn't change any of my wiring, but before I got the Clifford brain unit to at least unlock my doors. Now neither lock nor unlock works. Heres the wiring. Is my 457G faulty? What else could be the problem? 457G Light Green = Clifford Matrix Lock Output 457G Blue = Clifford Matrix Unlock Output Clifford Matrix Violet Lock and Unlock Input = Ground/Chassis Thanks, Nate

any ideas?

I would say a bad module( 457GW ) if your Clifford is putting out the right signals.Cris
