Hi I am new here so I'm not sure if I'm posting this in the correct spot, but I'm having big electrical problems with my 2018 GMC Sierra 1500. it started about 1.5 weeks ago, I turned my truck on one cold morning(-15C) and my speakers were making crackling noises with no music coming out at all, no door chimes or signals either. I noticed my volts were around 15.5-16, but it never went over 16. the music would come back on when I turned the engine off and just had it on ACC mode. I called my mechanic and he told me it was probably my alternator, so I paid to Get that replaced, he returned it and nothing changed. still having the exact same problems. I called him again and he took it back in and looked at it some more. The speakers now crackle for the first 5ish minutes of the vehicle turning on, and then eventually smooth out as the volts settle down to around 14.3V. I put in all new speakers around the truck about 6 months ago, with an Amp and subwoofer, but I am just now experiencing problems with it. I tried taking the power cable off of the amp, and its still doing it to the door speakers and tweeters. I am now out $1100 and still having this issue, if ANYONE could give me some advice or something I could try that would be awesome,

I have a 2003 yukon sle 2wd. The radio, windows, gauges on right side of the dash all stop working. The abs, tc and air bag lights come on. Now if you press the brake the radio and windows work. The gauges sometime come back on. The vehicle runs good now stalling issues or anything. Just wondering if anyone has any ideas what could cause this.
I have a 2004 Chevrolet Silverado 1500 4wd with the 4L60-e 4 speed transmission. Currently I have no speedometer and despite the transmission shifting very well, it skips second gear consistently (no intermittent functioning). This is the ONLY gear that it has issues with (reverse and the rest of the gears are good). Here is the story... I bought this truck being told the transmission was shot. Initially it would not shift past 1st and also had a functioning reverse. I had the tranny swapped with an equivalent from a suburban. It improved slightly but still there is no speedometer or second gear. NO ENGINE CODES have come up throughout this entire time including prior to tranny being swapped (this includes no ABS lights).
Here are the different problems I have found on the internet that I have tried to rule out:
VSS- A mechanic with a good computer states that all 3 Vehicle Speed Sensors read correct speeds in real time on the road Ignition switch- Already changed Fuses/relays- All appear to be intact and functioning Dash cluster- broken connections fixed restoring all function besides speedometer Transmission treatment- Lucas treatment put in in case this could be a sticky solenoid to no avail Grounds- All appear to be in excellent condition and no frayed wires visible Low Voltage- New battery in place
Help me out! What I can see as being my next options are either changing out the ECU or the wiring harness, neither of which I am desiring to do. Any recommendations from your experience that I may have missed in my internet reading?

Hello all. I own an 18 Silverado 1500 LT , double cab, 6’6” box, 6 spd transmission, I have opted to put 26” status alloy empire wheels with tire size of 305/26/30. Stock transmission gave out. They said torque converter and pump went out then everything else went with it. Was able to replace the entire unit with a remanufactured from GM. 1 month later, back to the shop (dealer). They covered the repairs because it was under warranty but if it goes out again they won’t because they believe it is the rims causing the trouble. However they will cover if it goes out with stock wheels. Which I will be putting back on. Has anyone else experienced issues with this type of truck and 26” wheels? I did research the “Unsprung weight” makes some sense, however only the transmission gave out, not my drive shaft, drive shaft knuckles, diff, just the goofy transmission which I know the 8 speed has had their share of ongoing things. Anyone with info ,thought , something sketched on a cocktail napkin would be greatly appreciated. I do thank you all for your time on this.
New to the forum. I have an issue with my truck. 2015 GMC Sierra 2500 HD. Just put on tow mirrors. Stock mirrors had full options (integrated blinker, heated, power adjust, power fold in, and puddle lights) My tow mirrors have integrated blinkers, heated, power adjust, manual fold in, amber marker light on back and reverse LED. My issue is, my reverse LED's do not work. I have a cargo light button which turns on the cargo light in back but not the reverse assist lights in the mirror. Is there any way to make them work? A trick or anything? Thanks!
