Hi all,
I have a 1998 Lumina 3.8L with around 114k miles on her. The AC worked fine but lately the air will only come out either on the defrost setting or the floor. When I choose the dash vents it will only blow air from the bottom. When it first started it would change from the dash vents to the floor when I stepped on the accelerator and once I let up it would start to return to the vents. Now (week later) it only blows out on top or bottom. Is it the vacuum resevoir? If so where is this located?
Thanks!
