what did it turn out to be? My AC will cut all fan speed no matter what I do and will stay off for long periods of time. It definitely doesn't work for me since it's 110 every day here. I've heard of a few others having this problem...so any idea on what the dealer replaced? My dealer seems to be trying to take the easy way out and tell me it's a software glitch that will go away when the flash my car after the new steering wheel sensor goes in.
