Sounds like your heater core is leaking, does it smell like coolant when your seeing the smoke, and is your heater on?

Sounds like the defroster vents blowing whatever... I actually had tree leaves inside the heater core next to the heater blower motor relay resistor. The relay resistor coils got red hot and set the leaves on fire...smoke everywhere. Fortunately the blower motor relay which controls the blower speeds blew most of the resistor coils so that only the high speed worked. In the Tech Library section is an article on how to change the blower motor resistor. But when you do, be sure to use a strong vacuum to suck out all the debri, leaves, etc. next to the heater core. It's really tight in there but I was able to tape successively smaller hoses to my outdoor vac and suck it clean. If the heater core was in the drowned body then likely that junk collected in there and is now smoldering or burning. Just my guess... good luck.
