Hey, my ac have blower speed issue, the rest is working like it should and i have change a resistor as well but still my fan speed number 2 aint working 
. Anyone had this issue before?

Re: civic eg fan speed problem
Make sure there is not a mouse nest or other debris in the duct, because that will burn out the new resistor. The resistor needs to be cooled by air flow from the fan.
The resistor and switch are in the ground side of the motor circuit. The switch grounds one of the wires to the resistor depending on the speed selected. The taps for higher speed have less resistance.
On '98 or newer (USA versions anyway) the circuit is electronic. The "resistor" is actually a transistor and operation is completely different.

If 1, 3, and 4 work and you've already changed resistors I'd suspect a faulty climate control.
Electronics are not my forte however.
