So i have an extremely odd issue with my 02 lancer es atm. and im hoping its not due to whatever the tweak person i bought it from did. he had told me he installed an aftermarket audio system in the car (cant tell if he just meant the stereo or the speakers aswell) but in Tuner and CD, the audio works in all speakers perfectly fine... but in Aux mode, there is 0 audio on the driver side. I've tried different aux cords, different phones, checking its fuse and the connection on the back of the stereo. sure theres some jank wiring back there from him (like extremely jank) but it works. sorta. theres a couple of wires that come off that dont lead to anything but he had connectors on them so it seemed at some point there was something they were connected to? I can try and check if theres a missing cable that fell from the splice but if that isnt the issue im at a loss
