How do you fill freon - Weather King 10AJA2501AH Air Conditioner

Do you mean the compressor?

Assuming there are no leaks, you could just need a little freon. But, If the fan (on the radiator) is not kicking on then your compressor may not come on either as it needs the fan to run to help keep the compressor cool. Typically it stems from being low on freon though and Autozone sells freon you can self administer but I would advise asking someone familiar with adding freon to help you so that you don't over fill or try to fill it from the wrong port.

There are two 'nipples' for your Freon system. You need to determine which is the low pressure side. I'm more concerned with the pump not turning. You may need to replace it. If so, you're better off letting a mechanic do the job. Otherwise you'll release Freon into the atmosphere. Expensive and environmentally unfriendly.

Take this to the dealer where they know what they are doing.

Freon is not installed with psi. It is installed by vacuum. Proper installation includes vacuum system (if empty of freon) and checking to make sure it holds vacuum for 30 to 60 minutes prior to adding the freon..

line that goes to compressor is low side line out of compressor is high side
always fill on low side
also r12 hase been band for sevral years and should not be used
if this freon is r-12 conpatible or replacment then your fine
after leak been repaired and system pressurized and vacumed out
start engine put a/c to max blower motor to hi open windows
conect your fill bottle to low side open valve and system will start filling
when freon reach enougt pressure the compressor should start and draw in
the freon if it fails to start you could jump the low pressure swich to help draw in
freon when system has drawned its capacity shut off your bottle and disconect your line to fill
cap off the valve
if compressor fail to start you have another issus could be electrical
take CAUTION doing repairs to a/c system

this system has to have a rather large leak. for it to loose it's charge in that short amount of time, is terrible. there are leak detectors that can sense a leak as small as 1 ounce per year. I strongly suggest you get the system leak checked before putting more "Freon" in it as it will just leak out again.

Go to your local auto parts purchase a a/c charge kit for about $69.00, find the low pressure(suction) fill port, there are two ports in every a/c system one is a low pressure side used primarily to fill a system with freon 123a or the like and it is the larger valve mounted on the line, then there is the dangerous high side valve, this is a smaller diameter valve mounted to a smaller diamet a/c line, this is under extreme pressure so donot attempt to fill this high side with freon as it can backfire on you and cause injury.
The low side fill kit will not fit on the high side port so thank godness for that.
start the vehicle put the a/c on full cold high blow fan speed, start filling the low side with a can of 123a freon+oil additive, which equals one pound of freon and check the inside a/c vents, getting cold? If its perfect then you are done, the system may have a very small slow leak and if it only takes a one pound can to fill it once or twice a year you are ok, if it takes more you may want to add a second pound can of freon 134a containing a dye additive that will work its way into the system and show you where the leaks are by exposing a color once it hits the air coming out of the systems defective seals etc.,also they sell a sealer + freon one pound can that can be used to try to fix the leak without having to get too expensive on the repairs.
A car's air conditioning system only hold like 2 3/4 pounds of freon, so in the event you happen to over fill the system a high pressure blow valve usually mounted on the a/c compressor will purge off the excess, but let me warn you they blow off without any warning and can startle you. Always think safety first, wear protective equipment. Work Smart, Work Safe.
Happy Motoring!!!

Its on the side of the freon holding tank, little black cap comes off, It is against the law to fill yourself due to ozone layer, only qualified tech can fill it for you.

1. check your fan belt, if your fan belt is in the normal position and no problem.
2. check your compressor and also check the clutch, it is locate right in front of the compressor, when you turn on your air conidition, the clutch should be turn with the fan belt. If it is not, that means your compressor had problem.
3. check fuse.
4. check the freon small flow window see if the lique bubbling too much, if it is means you need fill up R-12 freon.
5. you probably can not do it yourself, in case if you need freon and your compressor is completely empety, you need a special tool to **** the air out first and than fill up freon.
6. if your air condition is leaking,and you have to fill up a can of special check leaking freon with red colour first, until you find the leaking parts, fix it then you can fill up freon

2000 maxima is filled with R134, not freon. You don't need retro fit kit. Get couple of cans of R134 and pump it into the low side valve /small fiting, while A/C compressor is engaged. If your compressor is not coming on, jump the low side pressure switch to make the compressor come on and than the R134 will get sucked in to your system through the low side line. The proper way to do this is to put a/c system under vaccum for 15 minutes at least and watch for leak/gauges coming/loosing vaccum. Than pump R134 into the HIGH side valve with engine OFF.
