While driving to work (at 13 mile drive which took over an hour this morning-usually 25-30min in normal conditions), I noticed a few things: 1) The rear defroster goes off after a few minutes. Is there a reason for this? Is there a way to keep in on?-my windows kept fogging up on me after it goes off. 2) I couldn't go much over 20 mph on unplowed roads without the tires slipping. Does anyone use chains? I don't have the money for snow tires, so I am looking for an alternative. 3) When I open my door, some snow gets on my leather seats. I try to get most of it off. Will a little snow (water when it melts) cause problems on my seats? Thanks.
