    A/C problems/ B1324 code

    I realize that there are millions of posts about A/C issues, but I haven't found anything that matches or even helps my situation. Here goes..... 2000 Seville STS that has a compressor that will not kick in. I have a trouble code on the dash of B1324, A/C overpressure. I have cleared the code and it immediately comes back on. I can jump the compressor in the fuse box by jumping the relay, and the compressor and clutch work awesome. The air inside is cold as ice, but when I take the jumper out and put the relay back in, the air gets warm as the clutch stops working. I have tested the low pressure switch. The switch itself ohms out at 1.26 ohms, and the connector has 5.18 volts. I have purchased a total of 32 oz of A/C Pro R134. When I first attached the gauge from the A/C pro, I got absolutely no pressure reading with compressor/clutch jumpered. I added a full 20 oz and got cold air on the passenger's side, but warm air on the driver's side. I then added approximately 8 oz of the 12 oz can. Again, with the clutch and compressor jumpered, I get ice cold air throughout the car. But I can't leave the relay jumped as it kills my battery. I am currently working on getting a set of manifold gauges to test the pressures. Any help that anyone can give me at this point??? Thank you in advance!!!

    --------------------------
    the "problem" seems pretty basic -

    either you put too much freon in the system -
    and the high side pressure to too high -
    so to protect the system -
    the high pressure switch has disabled the compressor -

    OR - the high side pressure switch is defective -

    I am currently working on getting a set of manifold gauges
    to test the pressures.

    to diagnose the system - we need the following information -

    ambient temperature -

    with the AC set to 60* -
    fan set to medium speed -
    center vent selected -
    engine at a high idle - 1500rpm -

    high pressure reading -
    low pressure reading -
    discharge air temp at center vent -

    in the mean time - I would NOT recommend running the AC -
    with the safety switches by-passed -
    they are there for a reason -

    if you are looking to buy a manifold set -
    here is a great deal - for $60 - with shipping -

    or $58.61 - on ebay -
