Pump is located next to the spare tire, and if it has a leak in the locking system the pump is timed. The pump will run for app. 45 sec. Next to the passenger seat under the matt is a single yellow vacuum line, see where it branches off and test with vacuum and pressure with a vacuum gauge, find the one thats leaking nd replace, or you can cap it off if you would rather have someone who wont break the door pannel getting it off do it. The left side is on the drivers side same place.
