Hi Claudette The closing assist pump on your car is located in the trunk, near the upper left side of the fuel tank. This may also be referred to as the "power locking" pump but it is only for pulling the doors and trunk closed. A quick diagnosis is sometimes possible by removing the fuse that supplies power to the pump. There is a small fuse box in the R/R of the trunk, found by opening the little door on the inner trunk panel. I think it's fuse #9 you want to remove and re-install, but check the fuse card on the inside of the door. You'll probably find that everything will work fine for a short time after removing and re-installing the fuse. This usually means the pump is bad. Let me know how it goes.
