My wife’s 2002 Toyota Echo with 205,000 original owner miles on it has a problem where the AC fan does not blow out adequate air at highway speeds. When you put the selector switch to get the maximum airflow and have the fan on high speed, you can HEAR it blowing out but the air coming out of the vents is minimal. Please help anyone. It’s hot in FL but the car gets excellent mileage so we take it in lieu of our 2008 Tundra. Thank you.
