2015 Toyota Sienna Rear AC Not Cooling Due to Expansion Valve Stuck Closed

If your front AC is OK but the rear AC isn't working it could be the rear expansion valve.  A stuck expansion valve could cause no cooling if it's frozen closed or too cold /poor mileage / rough idle if it's stuck open.  I show you how to access the rear AC and how to inspect the components there
