noticed today that the AC air wasnt cold at all. First time ive had it on this year.
So i figured i'd head up to wally world and get a recharge kit

out cars use the old freon its r12 and its really hard to get
dude it cost more at a shop to have them refile like 150 lol its really not that bad
but you might get lucky and be onbe of the few that have the correct compressor to run r135
they also have some that you can run you just have to do the research
whaaat? i found 9 cans for 140 total lol. ya just got to search around
i belive it says it under the hood...
i just refiled my civics with r134a ftw!
ok i am OFFICALLY AN IDIOT
found this under the hood

You can go online and challenge the Mvac 609 (its practical open book test) cost me $25 and then bought the freon off ebay for like 13-20 dollars a can. To me it was worth every dime.
Before you put the R134a in change all o-rings especially the compressor and the evaporator/expasion valve o-ring. It is really simple process and higghly recommended.
Then o-rings deffinately need to be replaced.
The low pressure port is on the rubber hose front of the car. The high side is on the copper pipe near the battery. To fill it you need the AC compressor running. You may have to jump the low pressure switch to do this if it wont clutch up.

The only sure way to check your system is to put some gauges on it and see what pressures you have. No sense in charging a contaminated sytem.
lol i didnt change any o rings or anything when i did mine... just switched it on stuck the hose on filled it up until the one line got cold ... i now has very ice cold ac.. but i need a clutch relay as its going out lol

The weak spot on these cars is the evaporator/expansion valve seal, then the compressor.
I did the same thing in 1997 when I switched to R134a it works great but I had to add more to often. Its real easy to swap the o-rings and flush the system to help ensure a great tightly sealed system.
True , yeah its probably worth it to go ahead and replace them to be on the safe side, mine still had some freon in it though just wasn't cold cold so i didn't want to pay someone to suck the old freon out and didn't want to go to jail for spraying it in the o zone :lol:
Not to jack the thread, but what is wrong if the clutch doesnt kick in?
You probably have either an electrical problem or low pressure. There is a sensor for pressure, and if there isn't enough, it will kill the system. Electrical problems also become common as the car gets older.
Back to the main topic, If you do loose all of your refrigerant, it isn't a bad idea to get it properly serviced and not just add more. If there is a leak in the system and you live in a humid area, moisture can get in there. If you still had R-12, it could cause the system to become acidic and, well, aluminum and acid don't get along well. The moisture can also collect around the orifice tube or expansion valve and freeze, clogging up the system. What you generally want to do is run a near total vacuum on the system, and suck everything out. If it just won't suck down, you have a leak. Then you have to fill it with a tiny bit of refrigerant, and use a sniffer to find the leak. Once you repair the leak, you suck it down again and refill. Obviously this all requires some special equipment, but it is the best way to go. If you live in the desert though, you should be fine.
You can also go onto the ASE web site and take the refrigerant handling and recovery test for $15. Then you can be certified to handle both R-12 and R134a and buy the stuff in larger, cheaper amounts.
Get the certificate for R12 for $20, get the gauges for $30, get freon for $80. Now you're set.
