It sounds like the air distribution door motor is bad. If you turn the fan speed to low with the ignition on/engine off and try to change the mode to something other than defrost, you should faintly hear a motor running. If its making clicking noises, then it is most likely stripped. This is a fairly common problem with mode door motors. It will have one on each temp door for the dual climate control as well. Those ones usually last longer.

Air does not blow through vent on 1994 chevy silverado


Which vents, floor--defrost--dash? Can you hear the blower motor running? The squirrel cage could have broken loose from blower motor? There could be an actuator problem under the dash? If actuators are vacuum controlled and vacuum is lost, it might default to defrost, only blow out defrost vents.

Vent/defroster fan


A mechanic would check for power and ground at the blower motor.
Could be the motor, a fuse, the resistor, or fan switch.

1995 buick park avenue a/c digital face stoped working and now blowing cold air all the time


Quite possible a blown fuse. However there is also a blower control module located under the hood near the center of the fire wall. It bolts into the heater box assembly, not to far from the blower motor. You may have to remove the relay/fuse cover assembly to see it. They are known to short out and cause all kinds of problems. Remember though it could also be a simple fuse in that area or under the dash. The worst case here is the whole climate control system in the dash failed.

The a.c. on my 98 park ave. only blows on defrost ior the floor setting. I can hear the blower running and a little air comes out when in the dash vent mode but not much , i can however feel it leaking...


It's most likely a vacuum line, look under your hood (close to the cowl panel) for a disconnected, cracked or broken vacuum line.

In some rear cases, it could be the vacuum switch (in dash). Or vacuum diaphragm (under dash).

Hope this helps you ???

Almost no air comes from the ac vents but fan is on high. This happens on auto and also on econ.


The 1992 was prior to Buick putting cabin air filters in so there is not a possibility it is clogged. So more than likely your blower motor is going bad or your fan control switch is bad. Does this problem occur with heating as well as AC? Does it change if you switch between blowing on floor, face, window(defrost) If it doesnt change based on location of blow and type of air temp then I would start by turning fan on high and placing head (ear ) against dash in center of console area. Have someone turn fan knob from low to high with engine OFF...After goign from low to high and back a few times you can see if the blower motor is responding to signal from switch. Listen for a whine, squeal, rattle, or humm. A whine or Humm would indicate a bad blower motor... Squeal or rattle a bad squirrel cage/fan blower blades. If you hear no noise and no perceivable change in blower speed/noise then its possible your switch is bad. Unfortunately the only way to definitely diagnose either is to pull the switch from dash and use multimeter to test for voltage change and for blower motor to pull dash. There is a digital control unit for your car as well. Although rare sometimes the wires on this can loosen or it can go bad. But since you didnt state teh fan wasnt working at all and you are getting cool air, that woudl be teh last thing to check

Nothing blows out dash vents, but will blow out thru defrost nad floor vents on 1999 buick PA with dual auto air controls


check for a vacuum leak in the hose going to the heater controls. Goes from engine compartment, through firewall, into dash to control head. Also, has a vacuum storage canister under hood. When system fails, it defaults to defrost.

98 Olds LLC - AC works but fan air does not blow


If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps
