2004 Sorento - what would cause tail lights to not work, yet all other lights (signal, brake, etc) all do?
bad ground in tail light fixtures.
i have found in the manual that there is a battery saving feature and when it's on, it will shut off the taillights, i have gone through the manual and have done the sequence in which it asks you to do, i have managed to get them working that way but it's not an easy process and vey frustrating , open driver side door, turn off and on lights,.. thats all it said, and i had spent 30 mins to an hour trying that method before they turned on,
when my tail lights stopped working a friend told me to put in a fuse he had same problem,when i checked there was no fuse in the tail fuse spot .so i put one in,alls well now
I had this problem with my 2003 Kia Sorento. All lights except tailights worked. Some people may tell you to change the DRL (Daytime Running Lights Module) which is really expensive. I found a very and simple solution. Under your hood in the relay panel there is a spot labelled EXT. It most likely has a dummy fuse in that space. My space was labelled for a 15A Fuse so I removed the dummy and added a 15A Fuse and it worked! It bypasses the module and your tailights will work again.
This is known grounding wire issue with Sorento. Had mine replaced for free and haven't had any more issues.
