Why My AC Fan Pulsating????

yeah when i put on my ac in my y11 the fans pulsates the breeze . Is this normal or is the voltage breaking down or is the circuitry shorting??........i want to get this fix cause it kinda bothering me right now!!

or by pulsating i mean on whatever speed you have it on it does dip and get back strong and so on ....

i have scrapped down by the blower section and there was no air filter and dusty and thing .....took out the motor and cleaned it out and placed it back in ...thats how far i have reached ....lol

i realise this also is happening with my cousin mazda familia wagon XL (everything is the same as mine)so i not sure if it is a feature or something else.
What you peeps think???

*sigh* i have to repair ah motor now ....hope thise all but who can check this for me or how to check it ......was thinking to drop a power on it but i see it has a circuit board on it so can it be the circuit board failing????

connect the motor directly to a power supply if the problem is still there
replace brushes/motor

got through?

not as yet .....had to do some things but i realized that it only happening on 1,2 and on 1 you can barely feel anything but on 2 it blowing hard !! will have to check meh cousins one and see how no1 is blowing .....but it relly only pulsating in 1,2. Can it be the resistor/card thing that is for the blower(doh know if the wagon have it like the B13's and them)!
