What would cause a smell from the heater of a 99 Ford Taurus wagon that at first smells like a farm then turns to a maple-syrup smell when warmed up?

aleaking Heater Core. Interesting description! There could be multiple answers. To begin, the cabin filter could be the source of the farm odor. It is located under the vent cowling on the passenger side at the bottom of the windshield. Carefully removing the black plastic screws from the cowling. However, the maple syrup smell after warming up potentially could indicate a heater core leak. If you are occasionally having to add coolant or if your heater is only "warm and not hot" would be a clue. If you have a core leak or if it is plugged the entire dash assembly must be dropped to access and replace the core. Good luck!

AnswerBad thermostat, clogged heater core, or a defective heater control switch. If an engine has not been running long it will not have warmed up, the warmth from a car heater usually comes from the engine.

NO, it will not damage the vehicle engine by turning the heater ON before the engine has warmed up fully.

The engine has to be running and warmed up for the heater to produce hot air. So yes, you need gasoline to get heat from your car (unless you have an electric car).

With the vehicle warmed up and the heater on, grab and feel the two heater hoses. If only one is hot, you've got blockage either in the lines or in the heater core itself. If both are hot, the problem is going to be your blend door.
