My 2022 Sierra 3.0 liter Elevation was broken into in a fairly busy parking lot. The first thing they did was unplug the horn, which is ridiculously easy. Then they punched the driver door lock and were in with no alarm. Just a heads up. Im planning to put some sort of cage around the horn and wire connector just to make it a LITTLE less convenient for a thief to disable the horn/alarm.

The best solution would be to program the truck so that the louvers close when the truck is shut off. Anyone at @GMCustomerService listening?

Why not just add a second horn somewhere under the hood then tap into the horn wire that way if the horn was unplugged the second horn will still blow.

All you have to do is reach into the front grill and unplug.

 

They did the same to mine 2021 Sierra, ended up recovering, but can’t figure out the extend of the damages,

Could you guide me where is the horn harness?

they ended up removing the telematics module, that disables onstar

the dealer has it on back order

also, they cut a wiring on the back by the license plate.

just saw that the other day.


still figuring out that

Funny how GM will design the truck so to pull the spark plugs you need to disassemble the entire front clip of the truck but of course for something like this that never needs replacing that it is simple enough for a thief to easily access it and disable it.

Did you ever figure out how the horn was disabled? Mine was stolen and recovered. The horn was unplugged, I plugged back in and still no horn. 
 

also my rear park assist isn’t working and guessing they cut a wire back there like they did on yours. What wire was cut on yours behind the plate?

I wonder if the self-powered horn from the 'advanced security package' on the SUV's can be installed in a pickup?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
