So, I have a strange one fellas. The dealership replaced my headlights from an insurance claim. After the new headlights were installed the upper and lower light bars didn't work. They told me that it is controlled by the dash sensor. I made sure it was clean and still nothing. I took it back to have them do some Sherlock Holmes work on it. They got back to me and said the headlight ballast aren't compatible and they ordered new ones. All he could figure is there must have been a design change and the new headlights weren't compatible without upgrading those. 

 

Has anyone heard of this? This just sounds weird to me. Smells kinda funny too. 🤣

The only thing I could think of is that maybe they ordered you a set of the LED-signature headlights from the HD trucks? To my knowledge, the 14-15 SLT/Denali assemblies - though pretty much exactly the same in terms of exterior design - used halogen bulbs while the HDs were HIDs.

 

I was always under the impression that they would still be compatible though? Definitely worth checking out!

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.

      2021 vs 2026 handling (1500 X31 Sierra)

      By dennismc · Posted

      I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it.

      frustrating P0446 code

      By Old Bay · Posted

      So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.

      loose lug nuts

      By newdude · Posted

      Any grease on the stud threads of any kind?   Wheel studs should have NOTHING on them for proper torquing and so the nuts don't back off.     Are all of the mating surfaces clean?  So wheel, rotor and hub?     We've had plenty of trucks at work with that wheel, this is a first to me.  Makes me think they've got a lube tech putting anti-seize on all the wheel studs or some kind of grease, and they need to stop doing that.  To have 11 other trucks with the same exact problem.
