Jeff,
Have you figured this out yet? I ask because now that I am up in the single digit temps, and below, I'm finding my feet to be a little cold. The passenger side footwell is nice and toasty but the driver's side is suitable for hanging meat. If I had a nice warm pair of Sorels I probably wouldn't whine, but I only have tenny runners and combat boots.
Hopefully you've found a quick fix because it is a little too cool to hang out from under the dash trying to figure it out, especially since I have no garage to work in. I learned last weekend that you lose the fine motor skills quickly at sub-zero temps
What a PITA not having a place to work out of the weather.
