Just thought id give a heads up, as you know my a/c coil under the dash (i though) needed replacement. So after cussing kicking and bleeding it did not cure the smell i was noticing. However i did discover the fan control switch is prone to fail, it allows the smoke to be sucked into the vent. So if any of you happen to smell an unusual oder while a/c is on, check that switch, it will save some headaches.
