Is the same thing, one freezes and the other uses ducts to distribute air.. Not quite. Refridgerated air-conditioning works the same as a fridge, a gas is compressed and then cools the surrounding air as it expands again. Evaporative air-conditioning runs water down filters as air is sucked through...
When the heater resistor goes, your climate control fans will only work on the fourth setting. You can get a new resistor from any Ford Lincoln Mercury dealer, though they may have to order one.
