93 impreza, blower fan on 4 speed only

[njdrsubaru]

Hey Guys

 

i just bought a 93 impreza with 125K miles, good little car, i had to replace my legacy because of money issues.

 

Well the car is great and all, but the blower fan only works on speed 4, what may be?

 

thanks

possibly just bad switch, just spray some contact cleaner though the gap in the button, or switch whichever, and it should fix that, but most likely neesd to be removed, and sprayed.

Check my response to another blower issue:

there's a resistor pack, usually located next to the blower fan. you will find your problem there. there's a small chance that the selector contacts are malfunctioning, but that's very unlikely.

I would bet your looking at a bad blower motor resistor, I've been thru a few of these in my life as a Subaru owner. It is located near the blower motor on the left side, it has two screws in it and a multi-plug wire. Remove it and you will find some springs, A coil also acts as a resistor, thats why there are large and small ones, this gives the different speeds. If you need a quick fix, and it is near then end of the spring, just solder it back to the term, it will be at a higher speed but fuctional. If you get a replacement, resist the urge to operate the blower with the resistor out of the housing, it operates at high temps and the blower cools it. Removing the glovebox allows this to be much easier. Good Luck
