How can I change the ventilation mode on my Honda Accord?
Take a look under the left side of the dash and you should see a 7 pin connector for the mode control motor. Hit a button, does the motor move? if it doesn’t disconnect the motor and apply power and ground to pins 1 and 7 this should place the motor into the defrost position. If it still doesn’t move replace the motor.
Why does my wife’s Honda Accord not defrost?
My wife has a 1999 Honda Accord. The buttons that let you switch the ventilation between face/feet/defrost don’t work. It is stuck on face so you can’t defrost in the morning. The buttons for face, face/feet, and feet don’t seem to do anything. The lights for feet/defrost and defrost buttons will light up when you push them, but nothing changes.
What to do if your Honda Accord air vent is stuck?
Running a self-diagnosis can help identify the problem. To diagnose the problem, press the MODE (VENT/FLOOR) button several times. The LED should flash on and off as you press the button. Turn the ignition and the fan switch to the “OFF” position. Set the temperature control dial on Max Cool. Push the mode control button and select Vent.
Where is the mode control motor on a Honda Accord?
Locate the mode control motor. The mode control motor changes how air travels through the system, depending on which mode you’ve selected. It is on the driver’s side under the instrument panel, and on the left of the heater case. The blower motor is on the right of the heater case. The mode control motor should be parallel to the left fender.
