ok so the other day im drifting around in the snow with my truck just a little bit. a few cookies a few fishtails and whatever. well the next morning after sitting in a heated garage all night when i start my truck the speedometer always go down and then up to the 0 position at stand stil, well this time it stayed burried at the -5 mark :smash: anyways i drive out of thedriveway and it starts working but its really notchy and doesnt work (well not even sure if its accurate) but it measures speed right? wrong today i get off work and it does the same thing only it stays burried even longer and this time it was 14 degrees out instead of 55 like in my garage. it makes no sense. where is the speedometer register speed from is there a way it could be cloged up or is it a bad needle. i also have a bully dog chip, and i have an aftermarket stereo that has to interfaces one to work with the door chimes and everything and the other to work with the steering wheel controls. No subs just speakers and a deck i dont get it but i need help and dont want t spend alot of money to get ripped off and have it break again or just get plain ripped off!

This phenomena only occurs on '04 GM trucks located in the Twin Cities or surrounding suburbs!!!

 

The speedometer on my '04 Z71 'Burb started acting up when it began to get cold (this truck sits outside, my wife's '02 'Burb sits in the garage....go figure!!)

 

There is a well-known problem with the instrument clusters in the '03+ trucks. The problem stems from a bad run of stepper motors used in the clusters. The only fix (that I am aware of) is to replace the cluster with new or remanufactured, or get the stepper motor replaced in your original cluster.

 

I have researched this a bit, and am going to be replacing the cluster in mine. The advantage to replaceing the cluster is you can go with a different style (Escalade, SS, etc) and also add the tranny temp guage if you like (the trucks have the temp sensor, just no guage). The installation is plug and play, and is very easy (under 30 minutes if you stop for a beer along the way!). Note that the cluster is the only place the mileage is stored, so that will be an issue if replacing.

 

If you are still under warranty, let the dealer handle it. If not, and you would like some ideas, send me a PM and I can let you know the alternatives I've come up with.

Dang, so it plagues up to '06?!?

 

Did you elect to go with the SS simply for looks and the tranny temp? I'm assuming the '06 is still under warranty?

ebay has a seller on there ElectraSource (gaugepros) who is selling the new GM 2006 SS Clusters for $248.00 w/free shipping. For an additonal $65.00 they will program your mileage and ship over night to you, I know I have one on the way :)

 

By the way they are shipping the new 2006 version with the orange gear selector below the gears not the older (2003 -2005) digital version.

 

Here is an ebay link to their current SS Cluster auction http://cgi.ebay.com/ebaymotors/ws/eBayISAP...mMakeTrack=true

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      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.
