Passenger Side Doors Not Locking / Unlocking

[sleblanc63]

Recently my truck, 09 Sierra, stopped locking or unlocking the front passenger door.... sometimes. NOW... it has spread to the rear passenger door!

 

Drivers side works... front and back..

 

Suggestions?

Probably the door lock actuators,we've been having a run on them!

Thanks. Is this a "do it yourself" for the mildly mechanically inclined?

I took mine back to dealer it was warranty work.

I've got over 40K miles... Trying to get it covered under warranty!

My bad. I figured a 2009 would still be under warranty.

Forgot about mileage.
