I'm looking for a fuse in my 2015 Honda Odyssey that is 0v when ignition is off. I thought the passenger side seat heater should be the one but I tested 12 V when ignition is off. Is this normal?
There are three fuses for the seat heater system
1) Passenger fuse box: Fuse 20, 7.5 amp. Supplies Seat heater control unit.
2) Passenger fuse box: Fuse 5, 15 amp. Supplies relay power pin.
3) Driver side fuse box: Fuse 26, 7.5 amp. Supplies to relay control coil.
Some have power key off, some do not.
