    Re: wheres the port to recharge the AC?

    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.

    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 clutch does come on, first time i tried it last week i pushed the AC button and you could feel the rpms drop alittle while it came on. Just didnt have any cold air coming out of it, same temp air that was basically out side

    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.

    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

    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.
