After driving this car for a while in hot weather, the fan quits blowing. This is a dual zone heater/air conditioning system. If you stop the car and let it set for a few minutes, it will get better. You can turn the control as low as it will go, put it on auto or sync, it doesn't help. Have had it to two different dealers and they don't know where to look. One dealer tried, the other dealer couldn't get it to replicate when it was in there, so they didn't even try. We had told them up front that it only did it after it had been run a while. So frustrating. Would like to find someone that knows of a fix.
