Heater question for the cold clime guys...

[Cool Hand Lurker]

I found a huge difference in comfort when I went from a 6 volt car to a 12 volt one. The 6 volt heater fan 'circulated' the warm air. The 12 volt fan blew the warm air. If you are going to drive in the northland winters and make sure the car starts and the car heats then you want to convert to 12 volts. Shivering is cute, but lips are blue, the ride is cold, and so are you.
