Sounds very much like you have a heater core leak, the a/f sits in the fins of the heater core until you turn on the fan, then it blows out in an extremely fine mist. Antifreeze will stick to your windshield. If you drag your finger across the windshield, you will leave behind an oily looking streak if it is antifreeze there. You can confirm a leak by, blocking or joining the lines going into the heater core at the firewall. If after a couple of days the "smoking" disappears, but returns after reconnecting the hoses, you have definitely got a heater core leak.
