Very low air flow through vents despite the fan working well

With the blower working on high a very low volume of air (heat/AC) comes through the vents.

    Yes, the flow is low on all settings,

    I have same problem. I had recently removed a floor panel to access the blower motor and have not taken the time to re-install the panel. So, I am able to manually work the actuators which result in an increased air flow through the vents now.

It is very likely that the Air conditioner evaporator core is restricted due to leaves or some other object may be blocking air flow like a plastic bag, does it do this on both outside air and recirculation setting?

My windows are not defrosting properly.


Do you have heat? Does the fan turn on? are you getting air from the defroster vents close to the windshield? If you have heat make sure the defrost control is working. I'd open the outside air vent and turn the blower on high speed. If there is no heat, the heater control valve is not working. Double check the radiator fluid tank, make sure you have enough fluid (antifreeze) Low fluid levels can reduce the hot water flow to the heater coil inside the car. If there
is no air flow through the defroster vents you may have a problem with the fan control, or the fan motor. Good luck.

On my 1998 olds 88 I don't seem to have a good volume of air coming from the vents. The fans blow the a/c is cold but just not good air flow. How can increase the air flow?


Hello and welcome to FIxYa!
You may want to check on the vents for it can be closed half way. If the vents are good then the problem will surely be on the blower itself. It can be worn out that's why the blower motor blows weak. Once replaced I believe you'll be good.
Hope this helps and thank you for using FixYa! Have a good one!

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

Air/heat blower is not working unless it is on high.


The heater resistor is probably faulty, its located near the blower fan

2001 BMW 330i..Fan for AC/vent not working?


it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
