I'm having an issue with my S5 and would appreciate some input from you fine folks.

My tail lights aren't working, but the cluster lights and the dash lights work just fine. The Illumination fuse is still good and as I was poking around I noticed the tail lights flicker on and off a bit. They came on for about 10 seconds before turning off again.

I suspect a wiring issue.

I checked for voltage at the tail light harness and got 0. I also noticed that my corner lights aren't on either, possibly suggesting the problem is ahead of that harness as well.

Do you guys know any common failure points or have any input as to where to look for tracking down the discontinuity?

In addition to that, my clock is starting to randomly flash super bright but I read that was a soldering issue. I don't think it's related, but maybe I'm wrong.

 

your headlight switch and possibly the wiring harness leading to it has failed. you'll need a replacement. An S4 switch will not work in place of the S5 either

 

also, replace the harness that connects to the switch. if you dont, you will burn up the switch.

 

You mentioned that the corner lights were out as well too. Were these confined to the rear or the front as well. If the fronts work but not the back then focus on connector X-23 as it mates two sides of the harnesses which powers these lights.

 

Thanks so much for the quick replies!

Originally I had thought it was just the rear half of the car that had the lights out, but I just checked and realized it's the whole car! All four of the corner lights are off, as well as the two running lights in the front.

Would this be more indicative of a headlight switch failure?

 

The pins will be burnt.
