Removed the VSP speaker to disable the noise maker. After testing with co-workers with and without, they couldn't tell unless I was going backwards that the Leaf was making any noise. I however, found the scrapping noise that thing made as bad as nails on a caulk board.
The speaker is easy to get to if you remove the front engine bay trim cover and the reservoir tank for the High Voltage Cooling system. I laid it on its side and slide my hand behind the driver bumper. A 12mm socket to remove the two retaining bolts, then I a plugged mating connector to cap off the unused connector in case I ever want to reinstall the speaker.
Interesting that the speaker is not sealed and has a paper cone!
I also added a DPDT switch into a blank dash switch cover. I added to one side a 220ohm 1/8W axial lead resistor the other I shorted. To the common terminals I spliced into the red sensor lead to the in cabin air temperature thermistor with a connector (so I could easily remove the mod if needed) to splice in my DPDT mod'ed switch. Now when off, the cabin air temp reads normal (through the shorted bars). When on the cabin air temp reads a bit low (about 10F because of the added resistance). Since I have to park my car outside, and as it gets colder, I like to have a super warm car. So far testing seems to be right at 88F rather than the 77F Nissan thinks I want the car pre-warmed to. This will also work great to melt the snow off the car. I'm at 700' and get snow a lot more than Seattle does.
I also feel it helps dehumidify the car given this is Seattle. I also seem to note I use far less energy on cool days keeping the car at 73F, maybe preheating the heater fluid is good energy management.
The in cabin air sensor was harder to get to than the VSP speaker. The manual gave great info where the clips were. All the switch connectors came off easy. There was not much extra wire to the sensor so I used a small sealed Deutsch DTM series 2-way connector to tap into the circuit. I used some 18AWG wire to run from the switch blank on the driver left hand side to the in cabin air temp sensor and connect to the Deutsch connector.
After 3 trips to work and back I love the super heated cabin early in the morning. Can't wait for the snow...
