    if your getting air everywhere else. say if you put it on defrost and defrost works or if you put it on floor and floor works then u put it on vent and vent doesnt work then its a vacuum leak i would check on the passanger side by your feet to see if there are a bunch of vacuum lines and that they are all connected

Why did my 02 trailblazer stop blowing ac through all the vents when, switched to heat it still doesn't blow air through the vents? I have no air flow what's wrong?? :(


First check all the fuses. There should be one for Blower or Heater. If all fuses are good, It is likely a bad blower motor or a switch to turn on the blower motor. Try all fan speeds in non auto mode and see if you get any activity. If you get activity on some fan speeds then it is the switch or sometimes called the blower motor resistor. If no activity, its time for a new blower motor. They are under the dash usually on the passenger side, shouldnt be too hard to pull out.

My AC and Heater blower isn't working in the front vents of my 2004 Chrysler Pacifica what is the problem


If the air blows out of all of your other vents then you have either had an actuator go bad which controls which ducts the air flows through, or the shaft that has the "flap" on it has popped loose and no longer moves which will only allow air to go to the vents that are not locked. The easiest way to find out would be to get under the dash and start at the fan and trace air flow til you find the problem.

Blower runs but no air out the vents


You may have some debris blocking the passage of the vents. You may want to open the dashboard to investigate further. The blower motor may be running but it may not be driving the actual fan.

Air and heat not blowing air through vents


Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

My heater stopped blowing this morning.


Your heater blower fan unit is in need of replacement.
It's a difficult job so take it to a service center.
