This is my first Nissan and it has all kinds of issues. My AC works but the rear AC goes from low speed to full speed on it's own. I have to bring blankets along to protect the kids from freezing. The rear blower turns on even when the AC isn't on. Don't know what to do except keep the kids warm with blankets.

The rear blower goes on by itself when I turn on the engine. The front blower is at off but the rear turns on. I have to shut off the engine and turn it back on for the rear blower to shut off. I only have 50,000 miles on the van.
