Stop blowing cold air on me!! | |||||||||||||||||
Don't you hate it, when you start your car in the winter, and the heater starts blowing cold air on you, making you even colder? Why don't they have the thermostat compare the temperature of the "heated" air to the temperature of the interior of the car, and only turn on the blower when the "heated" air is actually warmer?

One problem to consider is that even if the heater would blow air that is slightly warmer than the ambient air, it would still feel cold.
Pretty good thinking from the 10 year old. The auto industry agrees. Ford Motor Company addressed this issue in a climate control system in the 1980's. (Probably others have done or still do the same.) A sensor in the hose that carries heated water to the heater core was used, in a certain heater operating mode, to prevent the fan from blowing until the water in the engine had achieved a suitably warm temperature.
Our '94 Buick supposedly does that (just got it a couple weeks ago, so haven't tried that out.)
It wouldn't be too hard of an aftermarket addon either, as most cars have the blower motor and a dicsonnect for it in the engine compartment.
Why don't you just turn the fan off at the same time as you turn the lights, windscreen wipers and everything else off when you turn the engine off?
I was taught to turn everything OFF before I got out of the car.
My car is a 99 and it has an automatic temperature control that does not ever blow cold air on your face. If you set your temperature to 71º, it will wait until the engine is warmed up enough to engage the fan. Another reason to love luxury vehicles.
My 1989 Oldsmobile Delta 88 does this. Takes about five minutes from the time you start the car for the heater fan to kick on, and when it does, the air is at least lukewarm.
