My power locks and trunk won't lock. I have to manually lock doors and strap trunk down. I checked all the fuses and changed the battery. What else can it be?

Masterthe doors locks and trunk soft-close are both controlled
by electric vacuum pumps. central lock pump is under the rear seat and the trunk closure pump is in left side of
trunk. either bad pump or a leak somewhere in the vacuum
