Your blower resistor bad or the blower motor control switch is bad. no air flow from top vent make sure vent open.because you can manual adjust them not to blow air on you.if all is good.you have leaking vacuum hose or vacuum actuator.or air door stuck.the AC and HEATER control switch.is bad.its not allowing vacuum to open air door.

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.

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.

I am working on a 2003 Chevy Trailblazer and the vents just blow out warm air, and will not change to the defost vents or the floor vents. Can this be the blend door actuator? And if so where is it


yes it could be the blend door, could be broken, or the actuator, or could be the climate control too, if you know where the heater core is then you just found the blend door, goodluck. Thanks
