My low side is high and my high side is low. Vent temp is about 70 f. What is problem. Just got filled of freon too.

Hi Pooh, If low side is high and the high side is low, that is normally a compressor problem; is the clutch on? Good Luck?

you are correct. The video depicts it as well. Perhaps if arrows were drawn, it would help show direction of airflow. it's basically right to left.
