What kind of car heater blows cold air?
Heater blowing cold air? I have an 06 Altima 2.5S Special Edition. It has 58,900 miles on it (yeah it’s high mileage, but ALL of my mileage is interstate – very easy mileage). It’s getting kind of chilly here in Maine and I just noticed this recently.

Why does my car AC blow cold air then blow warm air?
But that cold air turns warm fairly soon after because the high side pressures build to the point that the high pressure switch shuts off the compressor clutch. Once pressures equalize, the high pressure switch allows the compressor to start up again. The cycle repeats over and over, providing a short period of cold air, followed by warm air.
Why is the Vauxhall Corsa heater blowing out cold air?
The problem with the heater on the Vauxhall Corsa (as well as the Renault Clio) is often that there is no power from the heaters at all. This issue has nothing to do with cold air coming out instead of heat. This loss of power is also a common issue on the Renault Clio. Or you may have a dirty fan that is stuck.
Where does overflow coolant go in a car?
You can do this by lifting the bonnet (the hood) and looking at the header tank, which collects overflow coolant from the radiator. This is a large tank, usually clear plastic, with a conspicuous cap, rubber hoses coming off of it, and “Max” and “Min” markings on it.

How long does a car heater keep blowing cold air?
Have a helper get in the car, and keep the RPM’s between 2000-2500. Make sure that the heat is still on FULL blast (highest temp, highest fan, floor setting). Keep it like this for at least 10-15 minutes. You should see the cooling fans come on eventually.

When the engine is fully warmed up, put the cap back on and take a drive to see if the heat output has returned.
Why does my car heater keep leaking coolant?

An air lock prevents the coolant from circulating properly and can cut your heat output. Solution: Set the heater to its maximum setting, remove the coolant tank cap and fill it to the proper level.
