SOURCE: My ac unit is working but will not blow air out of the dash vents. The blower is working

Hey man if the blower is working and air is coming from your other vents i have a few ideas.First i would start by checking your vent selection switch something may be stuck where the dash vents open. If the selector is fine you should try checking the ducting behind the dash it could have come apart or simply be cloged where it routes air to your dash. hope that is helpfull.

2002 ford explorer AC and heat blowing in dash, but very weak from the vents


On the motorcraft parts web site, you can blow up
a picture of the HVAC Blend Door Motors & locations,
as well as part numbers

You can get failed motor from Amazon

With knowing where the motors are located, try switching
the air flow modes manually, to see what positions do not work

Then you know what motors to replace

I also have professional scan tool software & can see the codes
for the motors in enhanced data.

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

Ac vent only blows at low rpm high rpm it will not blow.


You need a new Blower Motor Resistor located on the Blower Motor Housing under the dash on the passenger side floor board under the dash. They are fairly cheap and easy to replace, your switch is good. Get a Blower otor Resistor;)

2006 hyundai tucson ac barely blows it is really cold, but doesn't blow hardly at all


The electric motor is probably shot. Does it work when you switch between settings like vent and floor? If one setting works and another doesn't then you have a problem with the dampers in the dash and the dash needs to be removed. If the motor is shot, you can find is location by listening very carefully for any noises when you turn on the ac coming from near the dash board. You can also ask a local auto parts rep to locate it for you, they can also sell you a replacement if you need it.

A vacuum hose that controls the little door that switches where the air blows from is off, its gonna be a real chore the find which one and take the dash out to get to it, but you might get lucky and be able to look underneath the dash from the passenger side and actually see it, good luck

Heater control 98 chevy s10 blazer


These trucks have a problem where moisture builds up in the heater box then freezes. When this freezes and you change your heater settings it breaks the shaft for the blend door. If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke. To fix this you need to remove the entire dash to get the heater box out which involves discharging the AC and draining the coolant because the heater core and evaporator come out. Please rate.

Dash Vents wont blow as selected


THE COMPRESSOR IS SUPOST TO RUN NOT MATTER IF IS IN HOT OR IN COLD MODE SOME TIME THERE IS A POSITION WHERE THE A/C WILL BE OFF AND THIS IS ON THE KNOB CONTROL WHERE YOU SET DEFROST AR FT VENTS
ALSO ON THE THE SWITCHING FROM DASH TO FLOOR CHECK FOR ANY VACIUM LEAKS FROM THE ENGINE COMPARMENT SINCE MOST OF TIMES THIS IS CONTROLED BY VACIUM ACTUATORS
