1988 chevy sliverado 1500 air door actuator
 

I was reading a thread from "shawnvw" and i would like to know if anyone can tell me why the air does not blow out of the a/c vents as well as the defroster vent. I saw a part in "lmc truck" parts catalog and it was called the " air door actuator ". Is it possible this could be the part i need to fix my no air blowing problem ? The air from the lower heater section blows hard and good. Please help me...i really am lost. SHAWNVW...I REALLY NEED YOUR HELP OR SOMEONE THAT MAY HAVE HAD THIS ISSUE BEFORE. THANKS TO ANYONE THAT CAN HELP.....
