Should I leave the heater box out?

It depends, you Minnneeesooottaaa guys have a short cruise season, so leave it out. Here I can drive year round, so of course I'm gonna leave it in.

I drive til the snow flies, so I use my heater. My blower motor isn't hooked up right (haven't checked wiring, pretty sure that's whats wring with it) so I have to have a window open to draw the air through the car. Kind of sucks but only takes a few minutes and the morning/late night fog is gone. I too would rather have it and not need it, than vise-vera.
