I had the same problem on my 2005.Remove the fuse for that door and then open and close manually. Replace the fuse and it should start working.
stop by your local body shop and have them look at it, maybe the child safety lock needs to be switched off
The tailgate on my 2008 Chevy Uplander refused to open. The unlock fuse was fine. The handle pull worked fine. I could even hear the little motor that unlocks the tailgate whirr when I pushed the unlock button. But the gate would not release. Turns out the problem was the lock mechanism was jammed because it had dirt in it and not enough grease. From the inside, I pulled the lift gate panel out at the window so I could look down and see the lock mechanism at the bottom of the lift gate. I reached down and prodded it with my screwdriver until I noticed that parts of the mechanism weren't sliding back and forth like they should. I sprayed it with a silicone lubricant until the parts started working again. Finally, the lock unlatched and I could open the rear hatch. I could then remove the entire plastic panel and remove the lock mechanism. I found that the mechanism has lots of rubber and plastic parts which get chewed up and start to jam if not properly lubricated. I cleaned out the dirt with my silicone spray and thoroughly lubricated all the moving parts. The latch now lets go of the post very easily, and the lift gate no longer gets stuck.
