My 2015 Silverado 2500hd has a wimpy horn. Only one of the tones is being generated. It must be a loose connection because it comes and goes. Any easy way to gain access to the horns?

Mine too, when it's cold it seems worse, just like you said one tone. It was at the dealer and they said it was fine but it is intermittent so it may have worked for them. I'm kind of a horn guy, you don't get much time to screw around and I am on you. If I could put train horns on I would be in jail for depraved indifference from causing a heart attach.

I've had 3 sets replaced. All 3 times they were filled with water. I guess they've been replacing both (or at least charging GM to replace both haha)

That's what it sounds like. Maybe I'll see if I can turn them down or move them. No sense throwing a new horn at a bad design.

My 2017 2500HD Sierra had am intermittent weak horn it was mainly evident when I would arm my alarm. One day I got check engine light it through a code for loss of TCM link I took it in the dealer reseated and retorqued all the connections on the main bus harness that fixed all issues including horn. I suspect maybe they do a shotty job with some of the connectors in the factory

I replaced mine myself. I had to pull the grill and loosen the front bumper and slide it off the driver side just to get to the stock horn and wiring. Pain in the hind quarters but now there working and new

95% of the time it's the connection at the horn. A lot of times replacing the horn helps because you have a brand new connector on one side and it usually scrapes enough to make contact. I wouldn't bother. Get a small wire brush and try to clean out the contacts then soak them in Diet Coke. Blow them out and put Dielectric grease in the connection. Check function before reinstalling the grill and light bezel

      Aftermath of Repair of Leaking Brake Line

      By unit731 · Posted

      Thanks for response. Leak was right under drivers seat or thereabout.   Had checked by other mechanics and have read other information.   The solution can be a tad complicated and replacing multiple parts And with some.  The issue was still the same.   The brakes do work.   Just that the pedal is softer and goes further down.  But the brakes do work.

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
