Cold air source when airconditioner is off?

Hi, I have the following question about glanat'98 and would appreciate any help. I've noticed that with the air conditioning turned off the ventilators still blow cold air in when I put the air mode selector knob on foot/defrosting and defrosting positions. And the air is dead cold as if from air conditioning; but, like i said the air con. is switched off. When I turn the knob back to face, face/foot, or foot positions it starts blowing normal temperature air. So where does the COLD air coming from? After all it is almost 90F outside. Thanks!

PS: i will check for answers here, but if don't mind you could also e-mail me at: tombon_7439yahoo.com

Hello,

On most vehicles, turning the HVAC to "Defrost", and the temperature to full Hot will engage the AC. On the Galant, turning the HVAC knob to either full defrost, or foot/defrost causes the AC to engage automatically, regardless of the heat control setting (I tested it on my wife's car).

Mitsibishi probably did this because running the AC tends to dry out the air (hence the condensation water running out of the drain, under the car). Since running the "defroster" means you want to defrost (or defog) the windshield, drier air will hasten the process.

On my Ford, setting the HVAC to "defrost", and the temperature control to full "hot" does the same thing (even in the dead of winter, in Canada). Personally I think that's more logical. I can turn the temp control back 1 click, and it turns off the AC.

Hope this helps to explain it.

Jimmy
