There could be several reasons why hot air is not coming out of the vents in your car. It could be due to a malfunctioning heater core, a faulty thermostat, a problem with the blower motor, or low coolant levels. It is best to have a professional mechanic inspect and diagnose the issue to determine the exact cause and necessary repairs.
your blower motor is stuck on low
because when you first turn it on, hot air blows from it... thats just how it works, then after a while cool air comes
um...I know why no one has answered this yet, cos no one knows what the heck you are talking about!! Try rephrasing it!!!!!
the vents work because of the heat which can make the hot air balloon go up

Smoke, Mist or Fog will come out of your A/C vents on hot, humid days. The reason for this normal phenomenom is the cold, dry air coming from your A/C vents is lower than the dewpoint of the interior cabin. Basically what this means is that cold, dry air is mixing with hot, humid air and causing the smoke. This is similar to when you open your freezer door and see the fog coming from the freezer. This is a normal condition and will eventually dissipate once the temperatures in the interior cabin and the A/C vents start to balance out. One way to quickly balance the temperature out is to keep the A/C system on recirculated intake air. Hope this answers your question.
is it because of a lack of vacuum pressure?
The heat and AC system of your car has its outside air intake located in an aerodynamically high pressure area to naturally create air flow. This is intentional to create a natural air change inside the car. If the system is set on heat (or is broken) it will blow warm.
could be that your vent on your dash is open.it will pull outside air in and if you are using the ac the air coming in the vent is from the hot weather outside.........there is a little spinning knob between the vents , make sure it is closed
AnswerWater vapor will sometimes exit your car's vents when hot humid air passes through the A/C cooling system too fast for the condensing moisture to form into water droplets. This can be resolved by selecting recycled air from inside the car, but the vapor is not harmful and usually doesn't last long.
The air should be comming out of the defroster vents. If so, most likely, it is the vacuum line that controls the vents. It is on top of the engine below the air cleaner, and runs to the front right of the engine. Buy the replacment so you know what your are looking for.
what i am assuming is being talked about is that when you go to turn on the heat in a Seville, heat will only be produced out of one side of vents. there are a number of valves in a Seville which control wether the air that is coming out of the vents in hot or cold. in a Seville there are a pair of these valves one for the passenger side air, and one for the driver side air. the reason why only one side of the car is blowing hot air is because one of these valves has gotten stuck in the "cold air" position and needs to be replaced. the same thing happened on my car but the drivers side was the one not blowing heat.
