    Hello to all,
    My 2008 Yukon SLT seems to have a problem with the drivers door not locking. The lock moves up and down and the key fob works but if I lock it, I can pull on the outside handle and it opens right up. I found this out by accident. does it sense the key fob or do I have an underlying problem.
    Thanks

    Welcome to the forum from Iowa.

    it sounds like you have a bad lock actuator.

    Welcome to the forum from Oregon.

    Like Wade said, sure does sound like the actuator. Need to pull the inner panel and lookey loo.

    Welcome from NH. Lots of knowledgeable folks on this Forum who will offer their suggestions and perspectives.

    As stated above, I recommend that your next step is to remove the door panel, and 'see' what is happening, when you try to lock the door. The source of the issue should be obvious, once you have the opportunity to see it in action.

    Thanks everyone. I will pull the panel this weekend and see what happens. The actuator moves the lock up and down but it just didn't seem like it was far enough to engage the lock. Thanks again!

    The actuator serves both purposes along with linkage.

    when you have the panel off lube up the sliders with lithium grease and see if that corrects the problem
