    disable Climate Control override, in some vehicles (like yours) the HVAC system controls the fans.

    Is this a software problem or internal CPU problem? If I can command the fans via VCM what can it be? Any help greatly appreciated !!

    I did. Thank you. I received an email stating that it didn't look like the stock file. That is all I have. Can the problem still be determined?

    ok it was a bug, fixed in 2.23.511 or later, support will probably contact you when the download is available.

    btw, before you install the new version please change the climate control override value back to whatever it was originally.

    Thank you for the help. I really appreciate it. I emailed a couple logs with fan info and the last tune file to Bill. I know this broad question, But How long does it usually take for the software update?
