What comes to mind now that you've replaced the steering clock spring is that you may have damaged wiring caused by a rodent chewing on a harness or insulation of exposed wiring. I can foresee two or more bare wires with its insulation chewed off touching one another which could cause the flickering - or a single wire chewed in-two re-connecting briefly on occasion. Rats love to chew on wire insulation, and through copper wires...

Is the car parked outside or some place where rodents have access to the car?

 

yea It is parked outside so that's definitely possible, if you look towards the top of the thread when the issue first started, it would only flicker when I turned the steering wheel making me think something was shorting to ground, car is parked outside tho so yea it is a possibility.

 

How is your Grom VLine VL2 powered from the car's 12 volt power system?

I'd look into the problem being with the Grom VL2 itself or with a fuse block connection from which the Grom VL2 is powered...

 

the grom has its own jumper harness, however I did try unplugging the grom at one point no real difference that I was able to note, I do have a 16+ mouse controller the grom as stated. It's a very peculiar issue.

I can def try unplugging all the grom harnesses once more and note if anything changes, I'm not sure if theyres a relay that could've gone bad or something?

 

Yes, I would move forward in the troubleshooting process by eliminating the Grom itself (as well as its power connection, including the entire fuse block that may have been used to power the Grom) as a possible source of the problem...

 

Okay I'll get back to you than, the wiring is just at the back of the radio and the display basically it just piggy backs, basically just a 30 pin that connects to the 30 pin so I'll just have to rip the console apart this weekend.

 

If you used an empty fuse slot in a fuse block or wherever the Grom is connected to obtain 12 volt power - take a very hard look to assess the integrity of that connection as well as any subsequent section to look for possible abnormalities (e.g. fuse block section looseness, loose terminals/terminations, frayed stranded wiring, etc.).

Yes, please let us know the results after you are able to test it.

 

no so the grom uses the radios power you don't have to run your own wiring it just comes with a harness.

 

Okay, that's good as long as the harness is sound. I've heard that some people needed a replacement harness to replace a defective harness or a defective 16 pin (I think) connector, and updates have been needed for the firmware for some reason, but...

 

New head unit, no difference, to me it almost seems like it could be a ground issue but not 100% sure. Going to test the clock / head unit for ground and power

 

Sorry for slow replies havnt had time to do much
