76 Corvette Fan / Blower Working but Very Little Air Produced

[ykf7b0]

Hello, I am a new CAC member and a first time Corvette owner as of a couple weeks ago. I have bought my wife a 76 L48 / Auto that is buckskin exterior and interior and is cosmetically in great shape. It is a running/driving project that I am excited to be working on. I'm turning to you and this great forum for some guidance on an issue with the a/c - heater fan blower. The blower / fan is working good at all speeds including high if I wiggle the fan speed switch but the air produced through the vents is very little even with the fan speed selector switch on high. Please advise on where to begin with diagnosing the problem area. Thanks for having me on this great forum and I'm sorry for my first post being a question and not an introduction!! Greg

Thank You!!!! The car had been driven very little the past few years and I can't hear movement of doors when I roll the dial on the console.

Headlights are rotating up and down as they should. I only have a Haynes repair manual at the present time. I will begin my search for an AIM and factory service manual right now. Thanks!!!!

Not familiar with how the C4 a/c controls work myself.
May be better to ask in the C4 forum rather than the C3.

Belinda..Welcome to CAC!!!
I'm not that familiar with the C-4's
read back thru the thread
but I would check the same things as in the 76's....
if that doesn't work,start a thread in the C-4 section of your problem.
