Water may enter lilftgate ajar switch and corrode switch connectors on Jeep Grand Cherokee

Water may enter the liftgate ajar switch and corrode the switch connectors. This can cause the information center to display the liftgate ajar warning, the rear wiper to be inoperative, the interior lamps to stay on, the security alarm not to set, and/or the battery to drain when the engine is off. A new liftgate ajar switch is needed and the harness connector should be repaired.
