Why would a hotel-style heater blow cold and hot air at the same time and other times not work at all?
If the unit is a heat pump, and the fan switch is set to ON, the unit compressor will cycle to maintain room temperature. Thus, it would blow hot or cold, depending on if the compressor was on, and the thermostat was calling for heat. Turn the fan switch to off, and let the thermostat bring the fan on. Not working part, no comment on that.
The heater in your 96 Taurus takes a while to heat up and then doesn't blow very hot On really cold days If you turn the fan to high speed the air gets cooler with time like the heater can't keep up w?
First thing to check is the coolant level. It can be low and keep the heater from getting warn and still not make the car overheat. If it's full, too cold a thermostat. Worst case is a partially clogged heater core. A collapsed heater hose possible.

Where is the heater core on a 92 Ford Tempo?
The heater core is above/behind the air outlet for the floor. The heater core can be tricky to get out and take a bit of time and patience. Be sure it's the heater core before you take on this task. It will save you a lot of frustration. If your car gets hot but you still blow cold air when temp setting is in hot then you have either low coolant, a stuck thermostat, or a blocked heater core. If your interior floor is damp near the center front of the floor, then you most likely have a leaky heater core.
Why does your heater only blow hot air when you are pressing the gas and cold air whenyou are not?
Has to do with the rpms if it's idle not much power is giving out to the car from the fan belt to get very warm. Say next time you're in your car. Start the car give it a little gas where the rpm is almost at 2 rpms. Same goes for the a/c.

Why would a car blow cold air and overheat at the same time if the thermostat has already been replaced and there is sufficient coolant?
Could be a head gasket or a warped or cracked Cylinder head.
