2002 Pontiac Grand Prix GTP Question: air conditer problems

The a/c drain is located on the passenger side of the firewall (engine side) at bit past half way down. There may be a rubber elbow covering the actual drain tube. If you remove the elbow and insert a straightened coat hanger, that is the best way to clear the drain. Does your 2002 Pontiac Grand Prix have "dual" a/c controls? If so, the passenger temperature door actuator may be stuck.
