D@mn... usually works for me. You should buy a butane lighter. I know it sounds stupid, but it works for me hehehe. I'm surprised no one's heard of that one
I do have to warn you though... you are taking advice from a southerner about ice.
Maybe you're frozen beyond the help of a cigarette lighter.
If you ever get humidified or sunburned out of your car I can help.
Off topic, but enjoy your leather interiors... nobody buys them here for fear of an a$$ cooking.
