fogging mystery

[Leah and David Mueller]

Dear "Zsolt"

Was it snowing so that the car, while sitting, accumulated some snow in the
fresh air or heater ducts?  If some snow suddenly melts, the air will get
pretty moist for a time. Especially if accelerating, the sudden air intake
may move the snow and moisture through quickly.  Just my best guess if not
you heater core.  Others may have better solutions.  No smell of coolant?
