Default whats wrong with my air conditioner/heater? it only blows on the 3rd and 4th fan?

i have a 93 integra 4dr. when i bought the car, the 1st and 2nd fan on the switch to turn on the air/heater didn't work. only the 3rd and 4th turns would work. so i thought that it was the blower motor itself that needed to be replaced so i went to the junk and picked up one and before i installed it, i plugged in the wires first but still it wouldn't work? only the 3rd and 4th switch would work. so then i thought it was the switch itself and i replaced that too but no luck? anybody know how i can fix this? maybe the one that i got from the junk was bad too?

Blower motor resistor pack. Usually mounted near the motor.

You have a very common problem. You need to replace the resistor pack.

Congrats on your diagnosis. You've hit it right ont he head, it's the fan switch, now replace it,

If it plugs in it is easy, if it is soldered on that is only a Little harder.

Remove only 1 wire at a time and re solder in the appropriate place.
