Hello,

Can anyone tell me why speeds 1,2 are not working but 3,4 do I have a Honda Accord SE 2002.

Thank you

 

It's likely the voltage control circuit for the blower motor that's faulty, there may also be two fuses for the blower.

Simply the blower is a 12volt motor and if on position #4 ( fastest ) the motor may be getting the full 12 volts.
On position #3 the motor may only need 10 volts to achieve desired speed , on position #2 may only require 7.5 volts for the desired speed and position #1 may only need 6 volts for the required speed.

You can check for voltage at the blower in position #1 & #2 but don't use a test light use a voltmeter ( multimeter ).

 

maybe your resistors might be bad might have to replace them check.....

 

I had an issue with the fan on my 99 EX V6 not working. It turns out that the resistor for the motor controls went bad. Honda replaced it for about $140.00

 

sounds to me like a bad blower motor resistor or fan speed switch

 

I have a 94' civic ex and my blower motor is shot, how do i go about taking it out along with putting a new one in?

thanks,

 

I also have a 2002 accord se with same problem (AC and heat on work on settings 3 and 4, but not on 1 and 2). I took it to midas and they checked it an said the blower motor resistor needs to be replaced. They said the part costs $200 and the total would be $300. I did some research online and found that you can fix it yourelf. The blower motor is under the glove compartment on the passenger side, but the pictures were from a 98 accord. Does anyone know if the blower motor is in the same location for the 02 accord? I found a new blower motor resister much cheaper on ebay.
