I've scoured the forums, and have tried some of the ideas with similar symptoms, but of course, I can find nothing exactly like mine.
2004 Silverado 1500 5.3L. Recent snow storm resulted in not starting the truck for several weeks, and the battery died.
I ended up jumping and getting it to the auto parts store. The whole drive, the DIC was all green squares, and none of the gauges worked (but the lights did). I replaced the battery, and I suspect the ~10 minutes disconnecting the battery "reset" the gauge. Worked fine on the drive home.
About a week later, I hooked up a 4wire trailer, and returned, leaving the trailer attached as I parked. The next day I went out and started the truck, the symptoms were back: All green squares in DIC and the gauge LIGHTS worked, but no actual movement of the gauges. I went back and unplugged the 4wire trailer, shut off and turned on the truck, and all was well.
So at this phase, I was suspecting a wiring/grounding issue with my 7wire/4pin harness. With the trailer disconnected, the gauges worked fine.
I let the truck sit for a couple days, did not connect a trailer or change anything from the last time I drove (when all was well) and the issue has re-presented itself.
The major issue is that the green DIC lights will not go off. I'm having to pull the fuse to avoid them entirely draining the new battery.
Some notes about my circumstance:
-Cluster was professionally rebuilt by reputable service in 2020 - all steppers replaced
-the cruise control stopped working late last year; the odd thing is it WOULD WORK if a 7pin trailer was attached. Weird.
-I've checked the grounding as best as I can with a lift right now, but it seems more like a parasitic draw somewhere, or power backfeeding from somewhere
I've checked the instrument panel fuse and have replaced it, although it was not blown. No change to issue
I would appreciate any help or clues on where to look next. Picture attached is with the keys out of ignition. The lights are just on eternally =(
Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle.
The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!

Hey Everybody. I’m about to have my 2014 Silverado AFM deleted with stage 3 cam upgrade, longtube headers, l86 intake, l86 TB, 3200 stall, custom tune. My question- is their other things I must do to go with these upgrades? Truck is 4x4 but will soon be lowered. Driveshaft? New Trans cooler? Bigger oil pump? Any help would be appreciated. Thanks in advance

I have a 2017 Chevy Silverado and I have been having trouble with the entire radio and screen .. I recently replace a bad HMI module that I got from infotainment.com and it solved the issue. Now the screen is back to black and the display where the gauges are says “audio off” any idea why ?? Anyone have this issue I tried everything. Maybe I need a new ACM module now? HELP !
Opening this up to disabled and other Vets. We need a place to share. Isolation is death and not a good death.
How are my Brother and Sisters making it work? I’m struggling tonight. I’ve done a lot and overcome much. As I age the pain is overwhelming. 62 YO 90% disabled VA combat vet of USNavy and USArmy. Never asked for help and for 42 years have helped others. My truck, the science of automotive technology helps me maintain my sanity. Any others here that feel the drain on the soul and body? My fingers and formally strac functions don’t function right anymore. I love the constitutional basis of USA but wonder have many forgotten the rule of law? UCMJ? Caring about others before self?
