John,

Sorry, but I think you have a leaking heater core (ouch!!!). Not quite an easy fix, as there is A LOT to remove to get it repaired (in/under dash, A/C line removal, heater line removal, some electric, etc.). I am sure you will get some more replies, but this sounds like one to bring into the shop.

Lets just say I have tackled this once on another vehicle, and now I won't touch a heater core changeout.

Let us know how it goes.....

Is the smell a heavy, sweet smell, like hot antifreeze? If so, see post above.
