Fans on high very little air flow
1997 Cutlas Supreme fans on high but hardly feel air flow what could I check ? Dash pots are actuating by glovebox.
Thanks in advance.
How do you take apart box by fan motor to check for debri ?

Are we talking no airflow in all modes(vent, defroster, heat, etc.)?
If yes, than I would assume debris or nest in front of the evaporator......
Drop hush panel on passenger side, and disconnect harness to blower motor....remove three 5.5mm screws, and pull the blower] straight down and out(may find debris in squirrel cage).....may need a flash light and mirror to look into the module to see if the evap has debris in front of it....
One time I looked up in there with a mirror and light, and these two beedy eyes were staring at me.....he was dead, but scared the crap out of me....

The evaporator IS IN FRONT OF THE HEATER COIL......check for debris.......if no debris is seen, you could have a refrigerant leak...oil coats the fins, and dirt attaches to the fins and blocks the air flow.....
