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.

Hello DGBenny,

 

There’s nothing worse than a wimpy horn. Have you addressed this with your dealer? If not, feel free to send us a private message, so we can forward your concern.

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

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
