Re: lol noob question (a/c)

The lower you set the control temp, the colder the air will come out (assuming you have pushed the Auto button to turn it on in the first place. Econ will not let the A/C come one). If you set it to 65 and it's 30 out then the heat will come on. If you set it to 65 and it's 90 out then the A/C will come on.

Re: lol noob question (a/c)

last part isnt true. Whatever you set the temp to no matter what the temp is outside it will blow out at that temp. if you set it to 65 and shut it off it will blow cold air to you feet same with heat if you set it to say 85 and shut it off it blows hot air to you feet. Econ mode if i remember still runs the a/c but at a bare minimum hence Economy mode.

Re: lol noob question (a/c)

Econ mode doesn't run the compressor. Only Auto and defrost use the compressor.

Auto mode uses feedback from the ambient temperature in the car to change the air feed from hot to cold to make the in car temp match what you put the setting to. If you put it on 70 and it's 80 in the car it will blow cold air to get it down to 70 and then it will try to maintain that temp. If You put it on 70 and it's 60 in the car you will get heat to get it up to 70 and again try to maintain that temperature. Econ mode works similarly but you will not get AC compressor cooled air when trying to cool the temp down, only outside vented air.

Once you turn it off though you are correct, if you left it blowing warm air when it was shut off, you'll get warm air. If you left it blowing cold air when shut off, you will get free air venting without heat.

Re: lol noob question (a/c)

Econ= Economizer. If the outside air is below the set point, then it will use the outside air. If the temperature outside is above the setpoint, then it will switch to mechanical cooling (compressor). That is how economizers work on building A/C units. I think it would also apply to autos, if not, then what is the difference between the vent button and an econ button?

The "VENT" control brings in air as is from outside.

The "ECON" mode is the same as "AUTO" but the compressor stays off during all operation.

Re: lol noob question (a/c)

so the control for temperature is where my outside temperature shows up digitally? maybe i have it maxed out but nothing shows up on that little screen until i press outside temp and it shows the outside temp. im guessing that will change all my temps?

You only get a display in the temp setting when it is set to "AUTO," "DEF" or "ECON." Or when you press the "OUT TEMP" button to see what the temperature is outside.

Here is an Owner's Manual you can download. It will explain everything.

https://www.wuala.com/dbarnblatt/Photos/SVX/

I sacrificed one of the several manuals I obtained in a bunch of SVX stuff I purchased. Every page scanned on a flatbed scanner. I scanned a 1994 Manual, because it covers both passive and regular safety belts, etc. So it it will apply to every year, except for a few minor details in the '96 and '97 models.

Please, anyone can download it, It's great to have if you don't have one... and it's cool to have an electronic version in your iPad, phone, etc.

AUTO regulates the temperature by means of the compressor.
ECON regulates the temperature with the outside air ONLY if the outside air is cooler than what the set point is.
If it is not, then you will have to set it to AUTO.

Auto uses the compressor
Unfortunatly, Econ does not.
If Econ does not reach your disired temperature,
then you will need to switch to AUTO.
Economizers usually do this for you automatically.

Re: lol noob question (a/c)

I know this is old but I just hooked my ac up (idler pully was froze when I bought the car). So, if it is 64 outside the air will not come on? It is 64 here now and I am trying to see if it works but the compressor don't kick on. The front doesn't spin.

Does it have freon? Have you checked the 10 amp a/c fuse under the hood next to the fwd fuse slot?

Re: lol noob question (a/c)

I haven't checked anything yet, I was trying to figure out how it worked. The shop said if it wasn't leaking, it should be good. I would say there is a good chance it has leaked out. We have had it for 2-3 years and its never had a belt on it. The pulley was froze so someone took the belt off.

Yeah, I would bet there's nothing in the system. I think once you start adding freon, the system will detect and start the compressor up. If not, you may need to jump the relay with a wire to turn the compressor on manually. Volvo's are that way when the system is completely empty.
