Every since I bought my 93 Legacy (1999) my blower switch has only worked on high. Is it possible to just replace the switch? Also, is it normal for it to blow a small amount of heat when the switch is all the way to the right (off?), when the heat button is engaged?

I don't see why the switch wouldn't be replaceable. A small bit of air (heat, if the temperature control is set there) will blow through the vents, due to the air being pushed into the intake. At least i guess this is what causes it, as it doesn't do it when parked and does it more the faster you go.

there is nothing wrong with the switch. Get a manual or do a search on this. There is a resistor block in the air box under the glove box. High speed is a direct feed to the blower motor. Lower speeds go through resisters. You need this block. Buy a new one, as used ones that work are few and far between.

Do you know where I can find a manual? I did a search on Ebay but couldn't find a service manual directly for a 93 Subaru Legacy. I have a Chiltons, but don't see this info in there. Oh, and is that something I can pick up at an auto parts store or does it come from the dealer? Thanks!
