If the fuses are good, I woild try disconnecting the battery for a few minutes to try to reset it.

 

Thanks! I'll give that a shot! due to a recall and totally unrelated, the car was given a new engine, however the problem persisted even after a new engine.

 

try that. the fuse is still good. but for whatever reason this "fixed it" for her (and me)

 

Thanks! I've tried that too, I'll try it again.

 

SAME! I have less than 3 weeks to return my lease and I need to resolve this horrible scuff (big scuffs) problem. Within 1 week of leading my Hyundai Tucson, I noticed scuff marks on the plastic in the back, from several bags of mulch the HD guys loaded. It only got worse and I now have deep scuffs and scratches. Surprisingly prone to scratches - both my Volvo and Mini Cooper carried much worse and never scuffed like this.

 

My radio quit in my 2013 Sonata. Fuse reset did not work, obtained a replacement unit (they're cheap at wreckers). Replacement was easy, lots of videos on YouTube. Here's one:

 

I have the problem radio working some times ... sometimes dont work... many electrical problems.... i reported to the dealer many times and they ignore me... ahh I have tle bulb lught burn many times (like 4 imes on the year)

 

Replace the tail light bulbs with 1156 or 1157 (the one with 2 contacts on the bottom) and it will solve the tail light problem.
2656 0r 2657 OEM bulbs are slightly brighter, but overheat the sockets, and burn out 5x as fast.

So perhaps someone can make some sense out of this and give me an idea where to look. It's currently at a Mom and Pop shop and I was told that my interior fuse box had a bad circuit and needed to be replaced which I did so with a used/tested one from Car Part Mall (eBay). ever since it was replaced I no longer have heated seats, or anything to do with the dash screen. No backup camera, no HVAC controls for temperature setting, no radio or even cruise control. The shop that replaced this insists that it is not operated and controlled by the fuse box.
the backup camera and radio are controlled by their own circuit
the cruise control is controlled by the PCM engine control module (the computer)

the backup camera is connected through the radio on its on separate circuit.


"none of which are controlled by the fuse box. we pulled the fuse box completely out and checked every single fuse and the surrounding wires that connect to the fuse box. All is operating as it should. The fuse box is completely unrelated to this happening. that's why it would be a separate diagnosis. $395. 3.5 hours worth of diagnosing if you want us to"
should I go with my gut and get it back to the dealer? (Update: it's Currently been at the dealer since Tuesday waiting for a technician to diagnose it)
