Hi all. I have a 2018 seat leon fr and both of my rear door speakers don't work. Obd11 says open/short circuit. Is this saying to you both rear speakers are dead. Find it odd both rear speakers don't work. I have an output of 7v from the connector so don't think it's a fuse, can't find the rear door fuse anyway. But I can't find on the head unit a fader to set volume only to come out from the rear to test which I find is weird. Has anybody had a similar issue and been resolved ??? Tia
