    Default ac problems someone help!!

    so i decided to check why my ac wasnt working first i found the clutch pigtail was cut, repaired it jumped the low switch and charged it up. now this is where i am lost, as the compressor cycles it pulls the pressure down on the low side to the point it cuts off, also while running going down the road you can really feel it cycling like crazy on off on off but while sitting still it cools perfectly but once you give it gas it cycles on off on off. anyone got a clue where to start checking things at i am lost!

    Maybe you overcharged it. Have someone put a gauge on it.

    there is a blow off on the compressor if it's over charged it should release the overage.you may have a bad expansion block that what regulates the pressures.
    i got a compressor kit from rockauto it had o rings the expan block compressor and receiver dryer hell the compressor even had the pag oil in it.
