Was this issue ever resolved for you? I have the same model 2005 Uplander V6, with the same problem. The left automatic sliding door won't open by the handle (inside or outside), the fob, the headliner switch, or the "B" pillar switch.
It sounds as though a solenoid engages, but there is no motor noise whatsoever. We have not removed door trim yet, and have never set the child safety lock-out.
