86 K10 Defrost Quit Working

[wolverine_22]

Defrost just stopped working now it just blows out the vents. When you feel the defrost you can barely feel any air. Took the dash off couldn't find anything, that I knew was the problem. Someone said something bout a linkage that might need wd40. When I move the cold to hot I see a linkage. But when I move the mode it just spins a dial right behind the control. Any suggestions would be awesome
