A quick way to diagnose airflow issues if the unit is in a slide is to remove upper grill and take a spray bottle and mist the upper heat exchanger. Do this about every 15 minutes for about an hour. If the unit works, then the cooling unit is ok but you need more airflow. I had to do this while traveling in 105 deg heat while in TX a few years back.
Don't spray too much water, just enough to cool the upper heat exchanger.
