In the cold weather, I have noticed that my heater takes a long time to get hot. Normal around town driving usually takes the temp needle to the middle in about 10 minutes, but the heater does not get hot until at least 5-10 minutes after that, and that is only the "vent". The "floor" seems to never get hot, it might after a while, but i never drive my car for long enough to find out. The "Defroster" is working like the "vent". Why does the heater take so long? Why wont my "floor"get hot? Iv noticed in my friend's Camry that the floor gets hot in about 5 minutes, so hot in fact, that we have to turn the heat temp down.
