1983 Crown Victoria Ltd What is happening if there is smoke coming from the ac vents in the dashboard, but don't have a smell. Is it fixable or is I’m out of money???

Evaporator coils might be clogged up and need a cleaning or the drain hole needs to be unplugged. Perhaps both.

If it is smoke it will have a burnt wiring smell, steam from a leaking heater core will a sickly sweet smell due to the coolant, unless your only running water as your coolant,(not recommended). So check the A/C drain as Brian suggested, if it is open and operational then you can try bypassing the heater core and see if it stops, if it does then you know the heater core is bad. The only other thing it could be is a freon leak but that will usually drive you out of the vehicle when it happens, and will stop when the freon is fully discharged.
