Hi I have a 2018 sierra 2500 hd Z71.

I have mirrors with power heat turn signals and power fold. If I buy the factory tow mirrors for the truck do I still need new harnesses? The dealer told me I would loose my power fold and they would have to program the mirrors to the truck? Any help would be appreciated thanks.

No sir.  That is very inaccurate info.  If you get the correct mirrors, my custom hardnesses, you’ll retain power fold, memory, and won’t need any programming. 
 

Here is the link to my harness.

Many dealers will provision the wrong mirrors too.

Do not order the mirror kit they have as an accessory if you want to use using factory mirrors.  Those will NOT have power fold.  

 

You need the individual mirrors for RPO code DQS.  For black cap ones you need 84228899 left and 84228900 right for gas engine or 84691688 right for diesel engine.  

 

For chrome cap ones you need 84691681 left and 84228892 right for gas engine or 84691685 right for diesel engine.  

 

If you are diesel and install a right hand gas mirror you will get a check engine light.

probably a little late to the party but I bought tow mirrors from Boost Auto Parts and they are amazing, kept all my factory features and added some forward facing lights, they're expensive but I'd say they're worth it

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...

      I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.
