Hi all,
I had my alternator replaced on my 2000 GMC Safari Van at a chevy dealership. The other day I noticed that the AC control that directs the air through the vents does not work. The air only comes out the defrost and the floor. The redirection control has no effect. It was working fine before the repair. I am thinking the mechanic left a vacuum line disconnected under the hood. Only problem is I don't know where to look. Where should I check under the hood?
Thanks in advance.
Marty
