    For awhile I had a problem where the a/c would stop working (the compressor
    only, not the blower) at speeds above about 55 or so. Now all of a sudden
    the entire engine starts 'pulsing' - meaning the ignition goes on and off
    several times per second when the car hits about 55MPH but only when the AC
    is operating.

    Additionally the ABS, upshift and check engine lights flash on and off and
    the temp gauge needle bounces widly while this is happening. I slow the car
    down, shut the ignition and restart and all's well - until I reach 55 again.
    If I run w/out the air conditioner it runs well at any speed.

    This is a strange one! Can anyone offer any ideas?

    Obviously a component in the a/c controller is going duff. Call in the experts
    to sort it out unless you have time and components available to swap out each
    part till fault clears.

    Cheers, Peter.
