I know there was a thread on this long ago but i cant seem to find it. It had to do with cleaning something.

Im trying to fix my ac problem when the unit is on interior circulation it barely blows out the vents

i have a similar problem but mine when its on vents doesnt seem to blow out much at all but everything else works fine

i have taken the controls out and looked at it and didnt see anything visually wrong with it so im not to sure what the problem could be either

Are all your blower speeds operating normally? Can you hear a distinct difference between Lo | | Hi?

Could be your blower motor resistor.
