Automatic Door Locks

[Brandon Scott]

I have a 08 Sierra GMC 4 X 4 that I am having probems with the front door locks on both sides. The key remote opens all open except for the drivers side. I have to use the key to open the other doors. Now when I hit the inside controls from the drivers the passenger front side don't open either. Now some time when I use the key remote the drivers side door lock will partially open. What do you guys think the problem could be?

I have a 2008 also and I'm having the same problem. There is no consistancy. It just seems to do what it wants, when it wants.

What did you end up finding out?
