    If you go to a Autoparts store they sell the recharge kits with a guage to tell you when your system is full. I think the one we sell is like $20 for everything.

    I ahve all of the stuff to charge it, and already have, just don't know the correct pressure. Those gauges aren't make specific. It say 40 is full...but it was 28 on my other car. I just don't want to put in too much as it is bad for the system.
    Thanks for the replies guys.

    The manual says:
    Low pressure: 18-28psi.
    High Pressure: 213-242psi.

    Is this what you're looking for? There are 27 steps in the recharging procedures.
    24) Adjust the refrigerant flow to maintain the pressure on the low-pressure side at 276 kPa (2.81 kg/ cm2, 40 psi) max.

    you dont add a psi. you flow it in at a psi. those cans are either 1 or 2 lb cans. its probally in that area. if you had the system disconnected you will have to take it to some one with a recovery station. one of the steps is to pull a vacuum on the system and then wait to make sure it doesnt have a leak. then add through the low side is your safer bet because you can do it car on or off. and make sure you position the can the right way to add either gas to the high pressure side or liquid to the low.

    check the service manual. if it just stopped working you should have a vacuum pulled. just my $0.02
