Is there really no wiring diagram publicly available?

[sonicrollin]

Hello,

I have been searching high and low on this forum and elsewhere for a wiring diagram for a 2015 Sonic Hatchback to replace some speaker wiring.

Does anyone know where there is one available?

Specifically, my driver's side tweeter and speaker are out and after testing the wires have concluded there is some bad wiring at fault.

Thanks.

Not sure, but probably up behind the dash... That's a tough spot. I'd check the wiring going into the door for breaks first - it flexes every time you get in and out. But, the tweeter is in the pillar, correct?

Thanks for the reply!

Yes, tweeter up in the A Pillar. No breaks in the door wire, but replaced the wire leading into the door boot connector. That didn't work. So working on the tweeter/ pillar wire now. If that does not work then i guess it's a deeper dive under the wheel. All other speakers working great.

Yeah no work. Dang, no idea what is going on.

I even tried tapping in along the driver's side kick panel, but that did not work either....

Anyone have any thoughts? Thanks.

Random thought, but did you check the balance and fader on the head unit? They are not in an obvious location, and you might just have that speaker turned off.

Yeah, i have a MyLink head unit and have tried the balance/fade to front left, to right, back to front left, and silence. No vibrations from any speaker tested (OEM, component woofer, and other coaxial). At a loss without trying to rewire the whole thing. But, there are quite a few clips and connectors in this vehicle, alas, ahhh.

Anything else you can think?

Thanks for the thought.
