    i just did a GM5 replacement for a local guy.

    he had a touring but same type of issues.

    his rear windows would go down but not up, holding lock button to close windows would open sunroof, rear hatch/trunk light..

    i replaced his GM5 with a known good one that had a same or higher software and hardware version and just flashed it with defaults (blank MAN file in NCS Expert). it coded the module as a touring and all was well for him.

    if you have coding software, go to the junk yard and get one for like $10. just make sure it has the same or higher software/hardware version as your original module.

    Thanks. Don’t have the needed software but really need to do some research in this area and improve my skill set. This is my second E46 and can see myself getting another once this one in used up. Having this knowledge and software would be awesome.
