Only blows out floor vents and not ceiling vents. has button to turn from rear floor to rear ceiling vents but doesnt work anymore. help plz!
No good answer here.... A Terazza has a different type of system and this problem is very common for this model.
Any answers at all for the Terazza or Uplander??
My Uplander has the same issue...No Blocked vents. Just no air out top vents. Bottom discharge only.
SOURCE: air will not blow out of panel vents
vents are blocked so air is diverted to other vents, check and clean if necessary

I had same problem on 2000 Lesabre blowing cold on passenger and warm on driver. I fixed it by adding more freon even though it had 28 pounds of preasure. Now it works great!
SOURCE: A/C blows cold on floor and windshield, not thru dash vents
This recently happened to my mustang and I found a broken vacuum line that connected to a "vaccum block". I'm not sure of the name but if you follow the vacuum line from the master cylinder it will lead ya right to it!
SOURCE: Air won't blow through front dash vents of my 96 Buick Park Ave
no most likely air vents are clogged
SOURCE: I have a 1999 Buick LeSabre. My AC blows cold air
the vents are run on vacuum so if you get the others just not vent sounds to me like you need to find your junction and see if all the hoses are hooked up. mine was passenger side above where ur feet go. All that usually happens is a hose came off and u need to put it back on sometimes they break but u will be able to see once u find it.
