I would not have predicted that, based only on surface area. Thanks for the good info!
That is pretty amazing. My back feels pretty warm with the seat on high. The wheel has never felt that warm. But that could be a difference in the sensitivity of the nerves.So, it turns out that the heated steering wheel uses more than a single seat.
Inspired by the Volt post in their forum, I decided to take my ammeter to by Bolt and measure what was happening with both the heated seats and steering wheel.
Elegant solution.. me likely.messes with the phase timing on the motor to get it to overheat a bit, and runs that through the dash heater core, on the way to the radiator.
