I experienced this problem as well. You need to get to the front vent duct at the front unit. I'll bet you find the insulating foam was not trimmed enough to allow good airflow. I trimmed mine and it did make some difference. However.!..!The airflow is still not as strong as the rear direction. It almost seems that the fan is managing to blow that direction. A small tower fan on the front console for additional air movement keeps us cool though; even in the hottest weather! I also agree that the proper air restriction with the vents is an added benefit.
