Check your climate control switches, and vaccuum lines. If you have electronic climate control, you probably need to have it serviced. Quite often in Grand Am's 91-2002 have had minor problems with weak linkages within the housing and routing of the climate control rod's and lines.

I have 2003 Grand Marquis that the AC blows mostly thought the defroster vents and sometimes will alternate to the dash vents but then right back to the defroster vents. What could cause this?
I had the same problem and then the fan quit blowing. It was all controlled by the automatic temperature controller. If I remember correctly it was referred to as a ATC chip. I purchased the chip on line from a used parts outfit somewhere in the north for about $50.00. It is pretty easy to install. It's located on the firewall on passenger side behind a heather hose
