Hello all, newbie here. I joined this forum so I can get real help with this problem. Ok bought a 1998 Cherokee TSI 2wd with the 4.0. Reverse lights did not work, checked for power and all that junk. Replaced the NSS which is the round one on this vehicle. Lights worked. Ran the truck around yesterday and today for a bit and the lights quit on me. I noticed it from the info panel in the lower console which said rear tail lamp failure plus a visual check on the lights themselves. What gives? I'm almost over it. The truck starts fine in park and neutral.

 

Can't believe no one has an answer.
