2011 jeep liberty lift gate Ajar fuse where is it located

*I have a door ajar light on and my horn going on and yet the lift gate on my jeep is perfectly shut and locked , so I wanted to know if pulling out a fuse would stop the alarm horn going on and the ajar light on my dash to turn off until I get it fixed. * when I start the engine it all stops but when I shut the engine off every thing goes on again so I have to disconnect the battery until I start it again , is there a easy fix for this , I thought maybe the fuse ?
