Recently a co worker pointed out to me my passenger side tail light was out at night time. 

I believe this is considered the running light function?

both bulbs are new and recently replaced. brake, turn, hazard functions all work fine on it but when its night time or I force the lights on the right side does not stay lite. 

Has anyone had this issue in the past or know of a possible fuse location that could be linked to this?

its a 2015 silverado ltz z71 if there is any difference in the trim fuse blocks.

Use a mulitimeter on the plug, see if you have power at the socket. From there you could see if you have power further down the line at the harness plug in.

Im sorry, which plug is it your referring to? Is there a separate plug for this function as the turn, break, and hazard functions all work perfectly fine on it?

 

attached is my engine bay fuse box.

Check for power at the light socket itself. Swap the working bulb with the non working bulb to see if you just have a bad bulb.

I have put fresh bulbs in and tested on the driver said light and they all work fine, so we know its not a bulb issue. 

I have yet to look under the truck for any corrosion. 

I did tape the harness on the back of my bed and a bunch of corrosion and dirt came out of the lights sockets. here is a picture of what they look like on the passanger side. 

I also was proactive and ordered one of the harnesses online.

is there a separate channel for all the power and why signals and breaks work but running and park wouldn't in this case?

Hi, just reading the issue you had. I have the same problem on the same truck. So you swapped the rear light harness on the one side and that fixed the problem. I also have no running light on the front too, on the same side. Did you have that also? As I feel if I swap the rear harness that may only fix the issue at the back not the front.

I have the same issue any progress? I am hoping not to have to replace the whole harness.

I have a 2008 GMC Sierra and I just happened to have the same problem and it just started 2 weeks ago now I changed up my license plate harness because that wasn't working and I changed out the circuit board at the back of the truck it's still a problem and I'll change the Lights still a problem just the running light only front to back What's going on. I have new harness  coming today for left and right back taillights harnesses change them out and see if that works if not it's somewhere in the middle one wire for the taillights

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
