I go to use my driver side turn signal and the DRL flashes at the same time the turn signal does. Only the driver side and only at night...what could this be? I just replaced the battery in the truck and noticed this right away. Never seen it before happen...

So what you're saying is, it does not switch over to amber and blink?  WOW, that's unique. 

 

Who changed your battery?  Stealership?  Have them fix it.  Isn't there a few relays adjacent to the battery?  Make sure that they are not partially unconnected/loose.

 

What does your interior indicator(s) do when you use your turn signals?

 

Does it do that when you lock/unlock with your remote? 

 

How about with your hazards? 

 

Out of curiosity (yeah, I know what happened to the cat), tonight, manually turn our exterior lights OFF, wait a couple seconds/minutes, and turn them back on AUTO.  Try your turn signal again.  Then manually, turn your headlights on, and see what happens when you use your turn signal?

 

Check the black plug on your BCM (left headlight/DRL/signals are on this one), verify that it is firmly plugged in and that none of the wires are loose.

 

I've dug through all of the PDFs that I have for these trucks, struggling to find anything to help.

Since the new battery is installed, I'd try disconnecting the neg & positive cables, and then touch them together for a few seconds or more. (Not to the battety!) This should discharge all electrical components. Them connect the positive cable 1st & then the negative & see if this corrects the issue.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
