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

      Scan Tool Recommendation

      By AndrewF · Posted

      I am in the market for a bidirectional scan tool so was hoping someone can help point me in the right direction. There are so many options out there it is hard to narrow down which make/model to choose.   I have always done my own vehicle work so looking to maximize capability with the scanner. Ideal price is $1k or less but would be willing to exceed if it opens up significant benefits.  Currently my 24 2500 is the newest vehicle but also have a few mid to late 2010s Subarus as well.    It seems that the Autel MP900 has a decent amount of features at a reasonable price?

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.
