Hi,
I was working with the fuses associated with the cigarette lighter/power supplies. The 20A fuses at #65 1n2 #127 listed are not for them in my 2017 I3. I can remove both of the fuses and the one under the dash still works. I cannot speak for the console one because it is out right now. What I REALLY want is to find the reason the power plug in the center console doesn’t work. I have inspected all the 20 amp fuses I can find (just in case another one was used. for the plug) and they are all good. Does anyone have any ideas?
Hi Mark, the lighter socket under the dash wasn’t working in my 2018 i3. I changed fuse 127, even though it looked ok through the plastic, and with a new fuse the socket worked fine.
