Greetings

 

I'm new to the club today.  These forums are great as I usually find the answer here before I go to the dealership and have to listen to their BS.

 

Problem- I have a '15 Silverado LT Crew Cab 58,000 miles and my passenger side front door lock just quit working. It doesn't open with the Fob, the driver side door lock switch or the passenger side door lock switch. Since it has no manual key door lock, I have to open rear door and reach in to unlock the door manually by pulling up on the nob. I'm assuming it's a switch, relay or actuator problem. I've owned many GM's and have replaced the window and power mirror switches before. Pretty simple to do.  I never got into changing the actuators as I don't feel like tearing apart my door. Has someone had a similar issue with just 1 door out of 4? What was the problem? I can take to dealership, but the ones near my house bends you over and doesn't ask permission first to violate you. 

 

I had the AC issue fixed under warranty, now I have this problem. With it being a '15, pretty disappointed in GM's quality lately.

Well if I had to completely guess. I’d do the door lock actuator. I’ve replaced a bunch of them. No way to be certain unless you test the circuits to the actuator. If you can do that, you can feel more confident about the repair.

Same thing on my 2014 Sierra except it's the drivers door. Actuator just quit working one day. Only 40,000 miles on the truck but it's out of warranty of course. From what i've read, big issue with them failing. They are cheap actuators and just quit. Just plan on replacing it. Local GM dealership told me their just a "problem area" and wouldn't do anything. Everyone thinks their should be a recall on these junk actuators for it's a safety concern. Doubt if GM will stand behind the issue and issue a recall though.

I had the auto door lock programed out on my '10.... could never get it done on my '14.

Would love to save the wear and tear from the auto lock feature by having it turned off.

2018 Silverado with approx 65K miles on it.  I've had the front driver and passenger door lock replaced all in the last 5K miles.  Now the rear passenger quit working.  3 failures in 5K miles.  What the heck!  Mines a double-cab.

 

Anyone got any ideas or are these just the cheapest things in the world.  About $300 to replace each one.

      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.
