Bypass it from under the hood till you can replace it.
SOURCE: Antifreeze smoke coming out heater vents
depending on how bad, and how long the orginal core leaked, it might just be residue in heater box, and if it got up into the vents, it will take awhile for it to dry out.

SOURCE: need to replace heater core in 1993 buick. water
the core is under the middle of the dash - look in under hood - you will see 2 aluminum pipes going behind motor into firewall - these are a/c lines - close to this you will also see 2 black hoses about thumb size - these are the heater hoses to the heater core - the dash might have to come out to get heater core from a/c fan housing
SOURCE: How to remove the heater core from a VW GolfMK3
there are alot of hidden screws holding the dash in. there are some up across the top of the dash by the windshield and defrost vents. also when you open the doors there are some in there. it is quit a difficult job I really dont recomend doing it yourself but if your not afraid to try and feel confident enough to tackle it good luck. it would be best to have an experienced mechanic do the job but it will cost over three hundred for labor. if you do it yourself go to a parts store that sells haynes repair manuals they cost about twelve dollars and are pretty helpfull.
Testimonial: "Thanks for the advice, I will find a manual and if gives some form of help I will do it myself. If not I will pay for it to be done. Thanks."
