    Default 08 Tahoe 5.3 door lock issue

    Hey all. Girlfriend has an 08 Tahoe 5.3 w/ about 5k miles. (Also has dealer installed remote start) About a year ago she had this issue w/ the right passenger door lock. Dealer replaced the actuator. Issue fixed. Now the driver door lock is doing the same. When hitting unlock on key fob, nothing. Bet every few locks and unlocks, it will work. (Regardless if vehicle was started remotely or not) Just wanted to get an opinion. 99% sure it's the actuator on this door. I think it's time for another trip to the dealer. Any suggestions?

    Had the same issue w/ my 2008 Silverado. Dealership replaced the actuators. Apparently bad batch of actuators.
