Hey everyone, So i just purchased my first Silverado used and immediately the gf and I notice a high frequency noise. The truck is a 2016 LT and when I test drove the truck we noticed nothing odd. after the salesman gave me a rundown on everything and how it works. He then put the truck in 4x4 auto and was explaining the 4x4 stuff and then onto onstar.
We left the dealership and immediately turned around and asked for him to hop in. He witnessed the noise and scheduled service to fix the problem. They gave me a bulletin for the transfer case and claim that is the noise when the transfer case is running. it sounds like a high frequency electrical noise. I have tried searching the forums and internet with no luck. I'm ready to try and just purchase a new switch and see if that solves the problem. any thoughts or advice would be great.
When I put the vehicle in 2H I get zero noise from switch, when its in 4Auto or 4x4 then you can here the noise come and go randomly.
This weekend someone slammed my passenger door probably to hard in my opinion. Not sure if this is the cause of the problem but the issue did start soon after. The Window and mirror lost power first intermittently, now completely. I checked the fuse and also didn’t see anything obvious as far as wires being loose or broken from the harness. Any suggestions or recommendations for a fix would be greatly appreciated.
I don’t like putting LED bulbs in the OEM housing if they are used on the road since they scatter the bright light and blind oncoming traffic. This install was not hard but more difficult than the 2014-2018 (and 2019 HD) Sierra.
1) unbolt 2 wheel liner bolts (10mm) and remove push tab to make room to work
2) use small ratchet and swivel to unbolt 4 screws (8mm) of the fog light housing and remove wire harness push tabs and remove bulb from fog light
3) use 10mm socket to “cap” the OEM expanding nuts and swap over the adjuster and only the ends of the 2 other retaining nuts
4) trim off all 3 tabs of the Morimoto pigtail with razor knife or box cutter (wear cut gloves and cut away from your hand and body) as you will install the plug upside down or the lights will not turn on
5) put it all back in and adjust light
associated pictures will be loaded below.
