I searched the forums for this, but when you search for any single term in the title there are far too many posts off the subject. In my 1999 360 Modena, is the air conditioner on when the button is OUT or is the air conditioner on when the button is pushed IN? Even the manual is confusing. You italian guys- stick with building them, let someone else write the book. Sorry, I haven't had to use the air conditioning and I had to kick it on today and it doesn't feel like it's working. Before I get into adding Freon or replacing lines I want to make sure the thing is on.
I'm too tired right now to search, but I wrote a big post totally explaining the climate control system. It's in here somewhere.
When the switch is pushed "IN" you will see it light up "STOP" which refers to the A/C being turned off. Hard to see during the day, so try it at night and you'll see what I mean....
In addition in order to have heater function the A/C needs to be on. Not that you need any heat in the middle of summer. Just FWIW.
That is correct. The only time you would need to press the "Stop" button in, is if you want just air (no heat or a/c).
Bizz is correct about the owner's manual, it is very inaccurate. As the manual states that you can also have heat function with the A/C in the off position.
Okay, I'm awake now (ha ha) and found the post - here is an excerpt: The key thing to remember is that you cannot change the temperature with the compressor off. Once this fact sinks in, it becomes easy. For example: Let's say the car is warmed up on a cold day and I want to heat the interior of the car quickly. The temperature dial is set to the coldest setting, the vent selector is on auto and the compressor is stopped. You turn on the compressor, turn the temperature dial to high, and the air will get hot and will be blowing very hard. At this point, if you want to, you can turn the right switch from auto to setting III and turn off the compressor, and the system will continue to blow hot air through the vents. If you want to turn down the temperature of the "vent" air at this point, you have to turn the compressor back on before you adjust the temperature dial. Of course you can leave the compressor on the entire time if you want to, but you don't have to once the temperature is at the desired setting. If it is a warm day with a cool breeze and you just want some cool, uncompressor (is that a term?) vent air coming in, then turn the left dial to the upper vent setting, leave the temperature dial on the lowest temperature, and turn the right dial to whatever setting (I, II or III) suits your fancy. Do not turn the compressor on. Oh, and turn the recirc off. FWIW, ICBW
I have tried that method and you will only have as much heat blowing out of the vents as the residue heat that's left in the heater core, it will eventually get cold again.
