I just bought a 2008 LTZ Avalanche. The front and rear passenger power door locks do not work with the button or the fob. Any ideas? Is it 2 separate problems or linked? Thanks, Scott

First welcome to the website!
You will probably find the answer in the problem section under electrical.....I would look for child lock settings and check fuses and relays.
Good luck in finding the right solution.

Sounds like your power lock control module is shot.  Might as well do both front doors at the same time.  Mine both failed within months of each other.

Sorry, the correct name is door lock actuator.

Let me know if you need instructions on how to replace.
