Hi, I have an airflow problem (in my heat/ac) in my 96 Chevrolet Lumina. I think I've narrowed it down to either being the rotary switch that selects airflow, or the blender(s) it controls. Is there a good way to test one or the other without having to dissassemble the whole dash area? Also, would I access the blender underneath the glove compartment (as I've seen a diagram in Chilton's saying that that's where the blower is)?
Thanks for any help you can provide, Louis
