Question about 2001 Pontiac Montana
It doesnt blow very well and turn it to other settings it does the same thing.
If the heater core is good and the blower works, the valve doors may not be opening and closing properly to direct air towards the proper vents. This may be because something has fallen in and is obstructing their movement. The actuating motors may not work properly, or the linkages that connect them to the mode doors may be worn or improperly adjusted. You can get a look at the mechanisms by removing the driver side knee bolster (two screws) and a lower trim panel on the side of the center console.
Be careful fiddling with the linkages. Everything is plastic and easy to break, and replacing the heater box requires removing most of the dash.

This is most likely the pollen filter. the access door is in the back of the glove box. It is probably clogged and restricting air flow. To test remove the filter and see if there is a significant increase in heating and air conditioning air flow.
