Air flow problems

Hey guys I have a 98 gtp that has heat and ac problems. When I turn on the heat or the ac I can hear the air flow but nothing comes out of any vents. Is this a common issue? I don't want to start replacing a bunch of parts since I don't know what the issue could be. Any ideas?
 


Look into a blend door issue.

If the fans runs and controls work, thats good and all thats really left are the blend doors that control the vents and if it pulls air from inside the car or outside.
 
if you cant change the directio of air flow, like vents to floor or to defrost. check for a busted vac line.

follow the one off the top of the sc to the fire wall. it runs down the fender and under the fuse box then into a wire harness and into the cars cab.

this line is what powers the air flow actuators, all vac powered.

hot and cold air is the blend door actuators. those are electric.
