I'm 16 years old that doesn't have a lot of money and I have a 99 Cherokee sport. there has been a constant noise coming from the trunk area and everytime it does this the locking system turns off and the doors start making noises and you cant lock or unlock from inside or from the remote. today it was making the noise for awhile and I was trying to put my key into the door since it wouldn't unlock from the key fob. so when I was putting the key in it was fighting against me and somehow I got it. I'm hoping someone can help me asap. thanks!
