89' 240sx heater only blows on full (4)

[faeasjepardo]

Hi Ladies and Gents, I have searched the forums for the last hour and cannot find the post I was looking for. It pertains to my push control unit on my 89' 230sx, I know there is a post on it somewhere as I found it about a year ago, but now I can't. Anyway my AC/Heater fan only blows on full (4), I know its something to do with the resistor, I want to repair it if possible. If someone could point me in the right direction that would be great, thank you.

usually means the resistors. the blower goes through resistors on the settin besides high but on full blast it doesnt

The blower motor resister is in the blower housing in the passenger side compartment. It has a plug with (4) wires, (2) screws. If you look in the factory service manual it has some good pics for you.
