Why do the front dash AC vents on a 1997 Lesabre close when climbing a hill?

Because U have a Vaccume leak-either a bad Vaccume hose going 2 the Vaccume Canister or the Canister.Sometimes they have small hard plastic hoses that crack or get brittle from Heat-IT only takes a very small leak 2 cause your problem,Even the Actuator inside the car could b bad or a hose off under the dash.

How can you fix your air vents to blow out air on a Buick LeSabre 1992?
Under the hood in front of the transmission dip stick is a vacuum line. If it is disconnected or split it will make the air vents not work. If that's not it check your fuses.
Ac is blowing from all vents except front vents?
yes
We have two return vents in each room.One close to the ceiling and the other near the floor.do we need to close the floor vents winter or summer?
Cose the high vents in the winter and low in the summer..
The Ac blows cold out of the rear vents but blows hot out of the front vents?
Usually is a vacuum problem. The vacuum works through the climate controls to make the vent doors open and close.
Why does the heater for my 2003 Honda Pilot not blow hot air out of any vents in the front but the rear vents blow hot air?
Your front blower motor has gone out. There is a front and a rear blower motor.

Why does accelerating open or close dash vents?
Because the vents are vacuum operated and when u floor it the motor losses vacuum
In a 1997 Buick LeSabre the ac blows out the defroster for the first 5 minutes then comes out the vents it could be a vacuum leak where do you look for it?

Your car has front and rear air conditioner but only 2 of the front vents throw out cold air what could it be?

Cool air flows from drivers side vents and warm air flows from passengers side vents on a 1997 Buick Lesabre?
Make sure refrigerant is fully charged. Does it have dual climate control? Perhaps passenger side sensor is not working properly
How do you get the air vent in the back seat to work the front seat works well in a 2005 Buick lesabre?
There is a conduit with a fastener at the end. When I obtained my 2005 Buick LeSabre my rear air vents seemed to blow less than I had expected. After further inspection, I discovered that the conduit was not attached to the vent stack. So I played with it until I got it to slide into the vent stack and it seems to work as I would have expected at present.
Why would the fan for the front air vents have stopped working when the other vents eg windscreen are still working fine?
vacuum leak?
