because maybe you car is either broken or the cold air is coming in from the outside
With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
Jaguars, depending on the model, have a seperate pump for the hot water for the heater. It's located on the left front inner wing, it is difficuult to see and remove. This is the most common problem on XJ40, X300, X305 and X308 shape jaguars. Same pump is used on X and S type too. Cost between £35-3&0 on ebay.
It doesn't really blow it out it just warms the cold air.
Your heater will blow cold air only.
The front expansion valve is clogged.
it wont blow heat itll blow cold air
you are low on coolingliquid !
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
The heater may blow cold air instead of warm air due to issues such as low coolant levels, a malfunctioning thermostat, a clogged heater core, or a faulty blend door. These problems can prevent the heater from properly warming the air before it is blown into the car.
heater core possibly plugged and leaking
No! Thermostat.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
you may not have the heater water hoses plugged in
