97 Century Vacuum Control Module

[rstiner]

My 97 century stopped blowing air from any of the ducts. The blower is running just blocked. Can someone help me torubleshoot it or at least tell me where its located? Behind the glove box? Under dash at the blower box? Where is the module vacuum supply from? I do not see and vacuum lines through the firewall last nite just before dark..... Please send email also to rstiner@yahoo.com if you would with any help. I will look again tonight if I know what I am looking for....
Thanks

Blower Motor is under pass. side of dash at the floor.
The vacuum line for A/C control is at the T/Body and goes to the cruise check valve then to a res. tank then goes inside the car on pass. side . HTH

Where is the vac electric solenoils locationed on the 97 century? I did not get to look around last nite it was raining cats and dogs....
I believe now its them or that unit. The air ducts do not change air flow when the control says it is. The strange thing is the blower is running and air is not coming out any of the vents like it should and I do not think the doors that move can block air from not coming out any ducts? Def,mid and floor I believe one should have air flow when the blower is running. This morning she said when she started the car air was blowing on high normally and she lowered the fan to medium did not change any duct setting and in 5 mins the air stopped coming out and did not come back the rest of the 45 min drive to work. When it happined the temp was not satisifyed? HELP.....
Thanks

This sounds like your A/C control head is not working not a vacuum problem .. if you have a vacuum leak in the sys. it defaults to def. and floor only and will not change modes. With no air flow out any vents I would remove the blower motor and check for a clog in the outlet and inlet of the blower housing then if o.k. I would suspect the A/C control head needs replacing .
Good luck and post what you find out . HTH
