Hi all, easy question for ya.. ( i think)

im new to the world of air con..! how should this work? i got st185 gt4 1991.
when i use the air con does it matter what temp i have the heating at? i mean if im blowing out hot air and i switch the air con on, should hot air stop being blown and only cold air be comming out....or do i have to have my fans blowing out cold air to use air con..

confused i am...please help!!

cheers,,,, :bigthumbu

If you switch the AC on, that just means that the ac compressor should kick in. To get the cold air you'll have to turn the temp down.

My blower motor pushes faster also when the button is depressed.

The A/C does two things, I cools the air and it draws water vapor out of the air. Most people don't know the second part. If you have the A/C on but the temp set to hot, then your air should be hot and dry, of course, about the only time that you want the A/C on and the temp set to hot is when you're trying to defog the windscreen. If you just want to heat the air, it is more efficient to just turn the A/C off.
