Hi, I hope someone can help. I have looked through the posts and found lots of problems with the blower resistor. My problem is different. I have lots of air coming in on all speeds. My problem is it's all stuck in the defrost position. The floor and dash board vents are dead. I have laid under the dash on the drivers side and watched the actuator move when I change the settings from defrost to floor or dash. It makes a clicking sound but doesn't change anything. Vacuum problem? actuator bad?

any help is greatly appreciated.

Thanks for the help,
Scott
