The backup lights on my 97 Jeep Wrangler do not work at all. The brake lights work, the park lights work, and the turning signal lights work but not the backup lights. My Jeep is an automatic. I have replaced the Neutral Safety Backup switch on the transmission but they are still not working. Has anyone had this same problem and know how to fix it? I haven't had this Jeep very long so I assume the backup lights have never worked. I would appreciate any help!! Thanks.
