I have auto climate and she has standard, and it is the same vac line that runs the flaps in the air system.
thanks

:( I'm having the same problem on my 94 SSE with the electronic temperature control. The AC only blows out of the footwells, defrost area, and rear seat vent -- regardless of what the display shows.
I tried jwikoff99'* suggestion, but I think I need more direction. When I pop the hood and look underneath, (standing a the front of the car) I see the brake resivior on the driver'* side near the firewall. Just to the left of that is a large, black circular "thing" about ~10" in diameter attached to the firewall. Is that the vacuum supply? I didn't see any loose tubes. Is this something I'm going to have to jack up the car first and get underneath?
I also tried willwren'* suggestion. I removed the bottom panel on the passenger'* side but saw nothing that looked like a "hockey-puck type device with several wires going in and out".
TIA

The reservior shouldn't be round. The round thing is part of the brakes. What your looking for should be squareish. There is a large black plastic piece that says Relay Center. The reservior should be in between it and the round thing. The top of it should come even with the top the the large plastic piece. On the bottom, pointing forward, should be two vacuum lines less than 1/4" diameter attached to it.

Hey, could someone who'* got an engine photo handy just PhotoShop an arrow onto it that points to the vacuum reservoir, and post it here?

In the course of getting the evaporator out of my '93 today, I had to remove the reservoir, and on the Bonneville it is in fact not the old-style round, spherical thing that the older models all used; it'* a big cube-shaped thing sitting on the firewall right next to the master cylinder vacuum booster. Sorry if I confused anybody before...
