Vents won't blow hot or cold air. Comes from defrost and feet when you put fan on.


It's the vent actuator, it moves the baffle that changes the direction of the air flow.
Here is a video of a broken vacuum hose that creates the same problem.

It could also be a failed actuator.

I have a 98 Buick Lesabre Limited. It blows Cool air, but not Cold.And also, I can't seem to make it blow out of the Center Dash Vents.


Cornelius, vent problem could be a pinched or loose vacuum line on controller,faulty AC vacuum motor, faulty AC programmer,etc. needs to be checked out by a good Tech, diagnosed and estimate on repair.
As far as vehicle only blowing cool air, issue could be blend door issue, plugged AC condenser core dirt/debris, low AC refrigerant, plugged AC lines internal, failing compressor, etc., again should be checked out, diagnosed and estimate for repair by a good Tech.
Check the attached links,instruction and guides, Good luck

Heat blows out of floor and defroster only not vents 93 buick lasabre


Under the dash you have the vacuum motors or servos or
electric door motors, for the hvac switching of air flow

So a vacuum leak or bad motor, whichever you have or binding
doors,also there may be linkage to some of them that gets into
trouble.

Hard to work or see things under the dash

If you have any electronics with an auto heat & a/c system then you
will need manuals to diagnose

The dash air vents on my 1995 Buick LaSabre do not seem to be blowing any air. Air flows only from the windshield and the floor. What could it be?


The distribution of the air flow works off a blend door which is operated by a motor. The motor is faulty or the mode switch in the control head were you set the mode settings is at fault

1995 Buick Park Avenue - A/C air flows through windshield vents only and not midcar or floor vents.


You have a vacuum problem either to the AC control head or a problem with the ac control head.
