First I'd like to thank evryone for all the help n info I've got from this site. '98 xtended cab 4x4 5.4. AC fan blows correct in all speeds, sounds like it goes to recirculate when switched but blows VERY little air @ dash vents either way. doesnt seem to have a filter. switches to defrost and floor ok. fan sounds like it should be blowin ur hair back. any ideas? Thanks

 

Where is the air actual airflow going when it isn't coming out he vents (if anywhere)? Floor or defrost?

Doesnt seem to be going anywhere.I know it must b but I cant feel it.
Ive taken the front of the dash off n checkd ducts across dash. wondering about duct @ blower motor housing. defrost and floor seem 2 blow ok.wish I could see a dash tore down to blower housing n ducts. might try a salvage yard.
