I am currently running into some issues with my 2018 Chevy 1500 WT radio/USB. These issues have slowly come forward over the past few months but really hit home after my local Chevy dealer fixed the well-known transmission and engine cam issues. They currently have stated that them working on that those two areas should not affect the radio and USB port. I am skeptical but looking for some insight from the forums.
Some background information and in-house diagnose:
Hoping someone might have some insight on this issue and possibly point me in the right direction. Last thing I want to do is bring it back to the dealership.
Some background information and in-house diagnose:
- Center consol is the fold seat style.
- No other USB locations in truck.
- Reset programs and let battery sit for 20-30 minutes disconnected. Nothing happened.
- Checked fuses. still serviceable but replaced anyways. nothing happened.
- Decided to pull fuse and put a blown fuse in both radio and USB fuse locations, and for some reason the radio stayed on... maybe that's my issue? Other than that, nothing happened.
- Replaced USB port with OEM, you guessed it, nothing.
- Replaced factory wire harness with OEM Harness. P/N: 23252399. Nothing happened.
- Took Multimeter to new plugs, fuses and everything in-between and nothing happened. Keep in mind I'm a mechanic not an electrician and probably was checking wrong pins on the wrong settings. All I know is that it beeped when checking fuses and beeped when I checked pins.
- There is power to the outlet and cigarette lighter.
Hoping someone might have some insight on this issue and possibly point me in the right direction. Last thing I want to do is bring it back to the dealership.
