Angela Summers (Eugene, Oregon) - 1984 Audi 200
Angela smells maple syrup through her dashboard when she has the defroster on. Bad news--she's smelling anti-freeze, and likely has a blown heater core. It'll be several hundreds dollars to fix it-- she can try getting through the winter without heat, or try BarsLeak or Alumseal to try to stem the leak. Tom also suggested trying a hibachi in the passenger seat. But she really should fix it.
