A/C Issue 1996
Tring to figure this one out anyone have any ideas?
Air is blowing only on the floor and defrosters when you first turn it on, there will be no air coming thru the middle vents. As you accelerate the air will start to come thru the middle vents. Then you have air coming thru all 3 areas.The guy that sold us the car said he could hear a vacuum leak noise but I have yet to hear it. There is no odors or anything else apparently wrong. The heat also works fine.
This is my dads vette that we picked up a couple days ago.
Thanks for your help.

All,
I like many others have a problem with their '96's blowing the AC out the defrost vent for several minutes before switching to the dash vents. The usual problem is the HVAC Programmer vacuum connector.
Sometimes the vacuum connector is just loose, but on mine I found that the soft rubber between the HVAC Programmer and the vacuum lines connector would "pinch-off" cause they are just too soft.
The fix I did cost about $2 and consisted of inserting a piece of PFTE tubing into the soft rubber so that it will not "pinch-off" any longer. The pain is getting the HVAC Programmer out and then back in. This costs time and back pain...but once done.....oh yeah!
I now have AC blowing instantly out the dash vents, and heat blows to the floor, again instantly...no more blowing air out the defrost unless I select defrost. It is so nice.

I had the same problem, I think that's what fixed mine. I didn't want to mess with it so I took it to the dealer and they fixed it without parts.
