I drove a package car yesterday that didn't have heat. It was only about fourty or so, not to cold but would have been nice to have a little heat. I did write it up on the dvr and the truck was to be pmi the next day. I was just wondering as what to do if it was really cold and if I could refuse to drive the truck. I was thinking if the windows fogged up it would be a safety issue. Just looking for some advice on this one.
