Been having this problem for awhile now, and can’t figure out what is going on. And having seen anything online to fix it, which is surprising.... I decided to join the forum, and ask...because being from Texas, I’ve actually seen many trucks with this sort of problem. Both Silverado’s and Sierra’s, used to think their lights had gone... but now that I’m experiencing it with my own truck, guess that wasn’t the case. 
 

so here’s the problem: some times, not all the times... Running lights only turn on on the left side(driver side)....but nothing on the right side. Including the back taillight. Everything, absolutely everything else works(headlight, the longer headlight, turn signals, break, everything)... but not the running light. And whenever this occurs, it does the same with the tail light not staying on, like it’s suppose to. Anyone have an idea what it can be?...image.thumb.jpg.3f187f7b9d301f32f690217523211ea0.jpgimage.thumb.jpg.22d2f941a6a16440bd82f3aa1bf03dd8.jpg 🙏

^ thanks. And yes, had seen that vid. Unfortunately it wasn’t that. 😔 

 

like I said, not sure what is up, but both the front light and the taillight on the same side, do the same thing, at the same time. 
 

Anyone know if maybe they share some fuse or wire? 🤷‍♂️

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      Tire psi

      By Chuck FB · Posted

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.

      Needing this part.

      I'm sure if you went to a junkyard where you go in and pull the part off the truck yourself, not a used part place where they do it for you, you can get that part on it's own.  Depending on if and what else you would be buying, and time of day, they might even just skip over adding it as a item to the bill.
