I have a similar problem. On the passenger door, when the outside pad or the inside button on the door is pushed, the window moves down a bit like it is supposed to, but the door won't open. The inside mechanical lever on the floor works, but the door won't open electrically.
The driver door works fine.
I took the exterior rubber pad switch off and cleaned up the contacts inside. They were a little cruddy, but not bad. When I reassembled it, there was no improvement.
To sum up, when the exterior rubber pad is used or when the interior door button is used, the only thing that happens is that the window moves down 1/4" like it is supposed to,.. and door stays shut. The door can easily be opened with the mechanical release on the floor.
Which parts need to be replaced?

Still doesn't work. It appears the solenoid (or little motor) inside the black housing has gotten a lot weaker. It tries to move the latch, but can't pull hard enough to unlock the door. The cable from the mechanical latch on the floor still opens the door fine.
I guess, then, I'll have to order a new one. The local chevy is OOS, and says they can have one in a week or two.
Which internet parts place has the best combination of price, service, and reliability? So far I have checked out GMparts.com and GMpartsdirect.com. They are about $50 cheaper than the dealer, and can probably have the part here sooner.
My suspicion is that the part number is 88956721.
Thanks for any help or info any of you can provide.

Well, I took the trim pieces off and took out the door latch assembly. Cleaned and lubed it all. It is riveted together rather substantially so there is no easy way to get to the inside to deal with the solenoid (or motor).

I took the door latch mechanism out, disassembled as far as I could, cleaned it up and lubed it. That assembly is riveted together so you can't actually get inside to see what is not working properly.
It still doesn't work. When the door button is actuated, you can see the little part inside the latch mechanism trying to move, but it acts as if the motor or solenoid, whatever, is just really weak and not able to unlatch the latch.
I will get a new latch from the dealer on Monday.
drat.

@Gyrobob, i know its 2014 its this is from 2009 but hopefully you remember the fix that you did on the door lock. I am having the same problem, its going down 1/4 of the way, but wont open all the way except if i do it with the release mechanism from the side of the door or truck.
I actually pulled the lock out manually and than with the door open pushed the open button and you can hear it trying to open but doesnt have enough power to open it fully.
If you can help me that would be great! Thanks

It sounds like you need a new latch. However, make sure the wiring from the power source to the latch is in good shape and all connections are sound. If you have a high resistance power path the latch won't get enough current to work properly.

The removal & installation is really simple. The door sill trim piece gets removed, then the interior side panel. Then remove the torx screws visible on the door jamb, and pull the latch solenoid out from inside the car. Remove the plastic cover (2 smaller torx screws), then disconnect the cables. Reverse the steps to reinstall. The only tools I used were a 1/4" drive ratchet, a couple of torx sockets, and a flat blade screwdriver.
My first time doing any service work on a Corvette, and it took about 15-20 minutes. I broke one plastic attachment piece on the door sill plastic, so I had to epoxy it back. I honestly believe GM engineered the Corvette interior to be assembled only one time.
Door release works like new now, as it should I guess, since it is new.

Doubt it is the BCM. Symptoms point to the door latch in the B pillar. The door lock system includes the door switch on the outside, the door switch on the inside, the door module which controls the window and the door latch and then the door latch itself. If everything from the switch to the windows is working and the latch makes some noise like it is trying to release you need a new latch. The manual door pull overrides the electrical portion of the latch so you can't use that as a way of eliminating the latch. Been down this road before with my car although mine was covered under warranty.
