    Can't Seem to Change HVAC settings

    Sorry if someone has posted about this before. I've tried searching A/C issues on the forum and I haven't found one that's close to me issue.

    I have an 2010 Luxury (manufactured in May or June 2010, original owner, just hit 66,500 miles) where I lose control to the HVAC system periodically (can't change anything via buttons, & HVAC tab on NAV screen with Weather isn't accessable). HVAC has never been serviced. There is no pattern as to when it happens. Fan may run, but no heating or cooling. Eventually, my control returns and I can make adjustments. I've noticed a couple of green oily spots on the garage floor (each were about 2 inches in diameter and are about 6-8 inches from where the water pools from the A/C). The spot doesn't appear every day I use the car. I'm guessing I have a small hose leak somewhere that only leaks when something overheats or gets aggrevated. The last couple of spots happened last week when lower Michigan was having high heat index days (one of those days was the most recent day when I lost control of the HVAC). I've identified the general area under the car where the spots are appearing.

    I had the car at the dealer for another reason and mentioned the HVAC issue. All I got was a shrug.

    Thanks
    Anyone have an idea why I lose temporary access/control of the HVAC?

    Just an update (for anyone reading this, hoping to find an answer):

    adamjeeps posted this link in another thread http://www.revbase.com/BBBMotor/TSb/

    I've searched through the bulletins and have not found an answer. I'm chaulking my issue up to electrical gremlins (count is now 6).

    Big thank you to adamjeeps for the link --
