Heater blowing heat when not on!

**MickG** · 2nd June 2006, 10:42 AM

Okay, who has figured out how to set the fan to just blow ambient air through the D2 blowers when the air con system is not on. From what I gather, if you have had the aircon on say auto (blowing hot or cold) and it has been blowing through the feet and dash vents, when you switch the system off, these are the vents that will allow ambient air to pass through and the others are closed???
On occasions though, these vents spill out hot air I can only assume comes from the engine bay? How do I just get the ambient outside air to blow through the system without it being turned on or even being set to econ. I just want free flowing air to come through the vents at the outside temp whilst I drive?

Aren't you glad it's winter and not summer now

mine does the same and the only way I have been able to stop it is by turning the AC onto auto and setting the temperature at an ambient temperature (when the fan speed drops to very low automatically) for a couple of seconds and then trning the whole thing off.

I have trouble getting any fresh (read outside) air into my D1 its a pain in the **** either air com or heater no fresh and no warm air to he hands only to the dash or feet - PIA i recon

Get a Defender then you just open the vent.

Hi Mick
I have the solution.Before you turn the climate control off you need to set BOTH temp settings to LO(the lowest it goes).
If you have the climate control set to any temp ie 24deg when the unit is switched off the heater will be on to a certain amount depending on the outside temp to arrive at this temp in conjunction with the aircon.If this temp is set and the climate control is switched off you will get warm air as the heater is still on.If you get into a habbit of setting the temps to LO it doesnt happen

Generally you don't even have to open a vent.

That would explain why sometimes it's cold and sometimes it hot

Cheers for the tip Andrew.

Aye, Mick

Aye, Mick

I seem to recall this issue when I had mine. I did not like the hot air on start up. The service manager pointed this out. Hope it helps.

Air distribution control
To control the air distribution within the cabin the ATC ECU signals the servo motor controlling the distribution flaps in the heater assembly to move to the flaps to the appropriate position.
In the automatic and economy modes, if the LH or RH temperature selections are set to LO or HI, air distribution is fixed as follows:
If one is set to LO and one is set to a specific temperature, to face level only.
If one is set to HI and one is set to a specific temperature, to footwells only.
If one is set to LO and one is set to HI, to face level and footwells.
When specific LH and RH temperature selections are set, air distribution is determined from the target air outlet
temperatures. For higher target air outlet temperatures, air distribution is set to footwells only. For lower target air outlet temperatures, air distribution is set to face level only. For intermediate target air outlet temperatures, air distribution is set to face level and footwells. When the air distribution is set to face level and footwells, the ATC ECU varies the bias between the footwells and the face level outlets, in three stages, to provide a gradual transition of air distribution from footwells only to face level only. The three stages of bias are also employed when the air distribution is manually selected to face level and footwells.
During warm-up, the air distribution changes to face level and footwells for a period, then reverts to footwells only.
The period of air distribution at face level and footwells can be cancelled by pressing and holding the on/off and defrost mode switches, then turning the ignition switch from off to on.
Pressing and holding the AUTO and defrost switches,
then turning the ignition switch from off to on, restores the period of air distribution at face level and footwells.

Have fun,

Trev.

Timed recirculated air
The timed recirculated air mode sets the inlet air source to recirculated air for 5 ± 1 minutes, after which it automatically reverts to fresh air. Timed recirculated air can be manually selected:
In the automatic mode, by pressing the fresh/recirculated air switch for 1.5 seconds or more; the audible warning sounds twice.
In the economy or defrost modes, by pressing the fresh/recirculated air switch for less than 1.5 seconds; the audible warning sounds once.
Latched recirculated air
The inlet air source can be latched to recirculated air:
In the automatic mode, by pressing the fresh/recirculated air switch for less than 1.5 seconds; the audible warning sounds once.
In the economy or defrost modes, by pressing the fresh/recirculated air switch for 1.5 seconds or more; the
audible warning sounds twice.
