    uhm, you're incorrect. please don't post bad info it's not helpful to people who are already concerned with a broken car.

    you probably have a bad BCM - body control module and your ECM, which is your ENGINE control module

    the a/c code means you're low in r12. get it converted to r134a (if not already done) and have it filled. your compressor is probably fine.
