Given, this car hasn't been driven in almost 7 years, I was checking all of the electrics today and while the blower motor works fine, no matter what setting I put the selector on, it ONLY blows out of the defroster. Any ideas as to why? is that a vaccum leak?
There is a vac line down near the driver's right foot that goes into the center of the dash. This controls the flapper door that divides defrost and panel. When it breaks or slips off, it defaults to defrist.
To find it, locate your vac lines going to the HVAC controls and trace them back.
