jeffao Posted March 18, 2012 Share Posted March 18, 2012 Can the temperature go below 65? Even at this lowest setting (ranges from 65 to 70-something) the air coming out (even with the a/c on) isn't very cold. I have test driven other 2005 legacys with manual controls, and can get the air to come out a lot colder. Is this normal for the auto controls?

jeffao Posted March 18, 2012 Author Share Posted March 18, 2012 will it pump out colder air even though the display only goes as low as 65? Link to comment Share on other sites More sharing options...
NWSPECB Posted March 18, 2012 Share Posted March 18, 2012 Never taken a thermometer to the air. Cold is cold. Hot is hot. The way you feel temperature of the air you feel coming out of your vents depends on the temperature inside your car before you turn your ac/heat on. If its hot in your car and you turn your ac on it will feel colder than it would if it was cold in your car and you turned the ac on. If you feel it isn't as cold as other similar cars then it probably needs a charge. Link to comment Share on other sites More sharing options...
frank_ster Posted March 18, 2012 Share Posted March 18, 2012 i think the 65 c is full cold it will continue trying to cool. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
jeffao Posted March 18, 2012 Author Share Posted March 18, 2012 In manual mode? Activated by toggling the fan speed with the system off? Link to comment Share on other sites More sharing options...
Max Capacity Posted March 19, 2012 Share Posted March 19, 2012 Push the recirculate button. when the A/C is on. BTW, I hate the Auto setting.

xt2005bonbon Posted March 19, 2012 Share Posted March 19, 2012 65 F is the temperature the system will try to reach. But the actual cold air that comes out from the vents should be much colder with the AC on and assuming your cooling system works fine. If not, then I'd believe you need a recharge.

wengermi Posted March 19, 2012 Share Posted March 19, 2012 i seen it somewhere on here but the newer (05+) legacys were switched to a smaller ac compressor. the older subarus usually need a recharge every 6-7 years and the newer ones need a recharge every 3-4 years. my 2007 had to be recharged after 4 years and i noticed it because it would not cool unless i decelerated in gear. after it was recharged she was like new again http://http://allwheeldriveauto.com/subaru-air-conditioning-explained/ Link to comment Share on other sites More sharing options...

rob-2 Posted March 23, 2012 Share Posted March 23, 2012 YOu can likely just buy a recharge kit. Should be much more than $40 Link to comment Share on other sites More sharing options...
xt2005bonbon Posted March 23, 2012 Share Posted March 23, 2012 YOu can likely just buy a recharge kit. Should be much more than $40 ^^+1. Even at Warlmart you can buy a can with a builtin gauge to check your system. I think it is even cheaper than 40 bucks. Link to comment Share on other sites More sharing options...
wengermi Posted March 23, 2012 Share Posted March 23, 2012 if you but a recharge kit it needs to have a high and low gauge. i over filled mine with just a low gauge and the ac started acting funny Link to comment Share on other sites More sharing options...

frank_ster Posted March 23, 2012 Share Posted March 23, 2012 ^ it starts off high then it calms down and almost goes to low for winter driving , windows start fogging up. i saw the new volks wagons have two auto modes , one more economical and the other more agressive.

jeffao Posted March 23, 2012 Author Share Posted March 23, 2012 just tried that. it blows noticeably colder air, but heres the question. With a gauge hooked up to the "low" end it reads about 33psi then slowly creeps up to 50 the the compressor kicks on and brings it back down. this cyle occurs about every 4 or 6 seconds or so. is this good/bad?

cseagle08 Posted March 24, 2012 Share Posted March 24, 2012 Last time I got an a/c recharged at a shop with the whole computer system done properly it only cost $65 bucks total. The recharge can from the store is real easy to overfill, or at least incorrectly fill if you don't know what you're doing. Plus, if you do have a leak somewhere the computerized system can usually figure out where it is based on some sort of voodoo magic. I could go into detail how, but it'd be a lot of typing.

frank_ster Posted March 24, 2012 Share Posted March 24, 2012 there is a sensor in the high pressure side, it reads if pressure its to low or too high. if its starting and stopping all the time its to high. let some out, fyi a full can is enough to charge the entire system these days. so if you were low it would need maybe a 1/5th of it.

jeffao Posted March 24, 2012 Author Share Posted March 24, 2012 How would you go about letting some out safely? Same concept as deflating a tire with the low pressure valve? Link to comment Share on other sites More sharing options...
rob-2 Posted March 24, 2012 Share Posted March 24, 2012 There is a high and low side to the system. You want to ensure you don't over/under fill either side. I'm not sure what the specs are but there is typically a few psi range that either side can be at. Overfilling with fluid is an issue. If you've lost a lot it's probably not a charge you need. As the system gets low however, slightly off spec it actually runs colder, and the unit will 'protect' itself by reducing the run time. As it will begin to freeze up. This extra load is largely protected, in the short term, by the systems natural ability to prevent freezing. Over time, being low will result in compressor burn out. Systems don't typically leak, they do loose a little bit over time. If you've lost a lot on a modern car it means you have a leak and a top up may ruin the system - IE putting to much fluid into the system. Remember it's part gas part fluid and is changing state through the cycle. A properly maintained ac unit will last years. On a 10 year old car we had the system was running a little 'warmer' than usual and it was off only 4psi on the high side. Fixing this with a little top up brought the ac back up to new. If you have a major leak I would avoid self sealing products. They are a short term fix. Run your ac in the winter a few times, not on days below 25f (unless required for safety) to keep the seals oiled. Link to comment Share on other sites More sharing options...
08SpecB_DE Posted June 28, 2012 Share Posted June 28, 2012 idling at a standstill You need to put the system on max cold, fan on high and in recirc. mode. You need to have the car above idle with the compressor engaged to get an accurate reading. Sorry, I know this is late and all but it may help someone!
