Climate control... not very warm when on HI

[antzleoncupra]

Hi,

After finding out the best way to demist the front screen, ive tried to send the warm air into the cabin by pressing that bottom right hand button (car with arrow) and a radiator looking button. Is this right? the only thing is, it dont feel very warm at all, and the front window steams up again, quite frustrating. lol

Also how do you keep the window from steaming aswell as sending warm air into the cabin? What do the two arrows up and down do on the control?

 

[meltonlad]

if your windows keep misting up just put the a/c on and that will clear it in seconds. also if you are misting up that much have you checked your carpets to see if they are wet ?

The up arrow direct it to the windscreen and the arrow down, towards your feet.

To demist, direct hot dry air on to the screen.

Hot - temp on high
Dry - snowflake showing (aircooling on - drys the air) This is important, one of the big advantages of the climate control system. Leave the air cooling off and all you have is a heater with computer controlled vents.
Screen - One way is to press the up-arrow, direct air to the top vents.

There is a quick way to do this. The top left button, above AUTO, is a one-button defrost program, which will do all this for you.

The middle button, the radiator-looking one, directs air to the middle vents only, those in the middle of the dash and on the rear of the central console. Not much use for screen demisting.

The bottom right button, car with arrow inside, is absolutely the wrong button to push if you have misted screens. It is "recirculate", and keeps all the moisture inside.

Thanks all for your help, especially yours Muttley. Thats helped alot.

Thing is, when i direct air into the cabin, and the climate control on high, it really isnt warm at all, feels cold and i have checked that the air cond is off too. Any reason why its cold when its set to high?

 

[Muttley]

Bear in mind that the heat comes from the engine coolant, so you have to have a hot engine before you'll get a lot of heat to the cabin air.

I assume you've used the temperature +/- buttons to set the temperature to HI. This should get the cabin uncomfortably hot.

The temperature is controlled by directing some or all of the air flow through the heater matrix, after it has gone through the cooler. HI should mean that all the air gets heated.

Are you getting lots of air through the vents? If the airflow is low maybe the pollen filter is choked. This may have a knock-on effect.

One possibility is that the temperature control flap is not working properly. This is controlled by a servomotor and is found underneath the heater ducts behind the central console. Not easy to get at.

The other possibiity is that your heater matrix is blocked.

Or failing thermostat, was in my case.

 

[Muttley]

True, that. Thermostat stuck open would keep everyting over-cooled. You should see that on the dashboard temperature gauge as well.

One other thing comes to mind. If your coolant level is low, then the heater matrix goes dry and no heat gets to the air. Worth a check of the coolant header tank.

 

[LEE69]

Have a look at these codes and see what temp the thermostat is

[antzleoncupra]

ill check the coolant level tomorrow, and i have run the car until the engine is hot and it still feels cold. Maybe its the stat, but ill ahve a look tomorrow and try.

Really appreciate your help you guys. Got the G/f moaning in the ear haha, 'What we gonna do when its winter etc, this car doesnt have as warm heaters as your other one bla bla bla'

 

[antzleoncupra]

where abouts is the thermostat and pollen filter btw? when being run for a while my engine temp stays at 90, but the top hose feels hot and bottom one feels cold????

 

[LEE69]

Thermostat http://www.seatcupra.net/forums/showthread.php?t=210977&highlight=thermostat
Pollen filter passenger side of the scuttle panel.

 

[antzleoncupra]

still had no luck with this one lads, winter is coming up soona nd i need my heaters working. Could it be my thermostat? The car runs at 90 on the temp gauge everytime and dont fluctuate. Is this the right temperature? The bottom pipe feels slightly cold and the top hose is very warm, however both are not hard. I have checked pollen filter and it isnt that. I really need some help. Anyone???

The bottom hose feels slightly colder, what a satement to be made, that meens the cooling system is working efficently as it goes through the radiator and the cool water comes out of the bottom. Have you definatly checked the pollen filter isnt blocked with crap? It may be a faulty control unit?

 

[Muttley]

I'll ask again, are you getting good airflow, lots of air out of the vents when the fan is on full speed?

Have you tried the temperature of the hoses feeding the cabin heater? The hot water connection is taken from the back of the metal pipe manifold that the coolant temperature sensor fits into, on the gearbox end of the cylinder head. This should run back to the firewall with the return pipe next to it. Test the temperature of both of these pipes - if they aren't getting hot, then maybe you have an airlock or a blocked heater matrix.

getting really good air flow into the cabin. At times when on hi it blows out a bit warmer then just fades off again. Sorry shaun for the stupid statement. I will check all what you said mutley and let you know mate. Where can i find the heater matrix? Pollen filter is clear and fine btw. Cheers for your help lads.

 

[antzleoncupra]

o yea, i checked them two pipes yesterday and they both get very warm. Coolant level is fine too. Maybe its the unit gone?

Not stupid, i didnt mean to come across as arrogant btw .

Heater matrix is behind the dash, not sure where on these but you should be able to see it from the passenger footwell. As i said it may be a faulty control unit.

uh, the arrow into the car is recirculation, and the 'radiator' one is actually the main vents :/

so what you're doing is just having the same air blow out of the front vents and round again..

what you want would be the one to demist the windscreen on full blower (top left).
failing that, you want the up arrow (windscreen vents) and then set the blower on full. although that is what the top left button does..

i know how to demist the screen now, its only the toruble of getting warm air into the cabin now mate

cheers though
