Hey folks, thanks for replying.
It's on a Chevy chassis.
I looked online for a picture similar to what we have. I couldn't find anything similar looking under rv compartment handles. Below are two pictures, the one on the right is similar to what we have. The compartments are like drawers, and the handles are like what are on the tailgate of a pickup. The "lock" simply prevents the handle from being pulled up to release the drawer. The drawer is not locked. A piece of the mechanism inside/under the handle has broken, preventing it's proper functioning.
