My 94 850 wagon with manual heater controls has a problem. The fan motor only works on highest speed, setting 4. I already checked the fuse for speeds 1-3. There's a relay (#2/24, I think) that turns the blower on high when the lever is set to 4, so it uses the normally open contacts (electricity only flows when the solenoid is energized). The wiring diagram in my Haynes manual is a bit unclear. Are you surprised? I'm not sure if speeds 1-3 go thru the normally closed contacts (electricity flows when soleniod is NOT energized) of that relay or not. Does anyone out there know if that's how it works? Also, do you know the color of the relay or its location? I'm assuming its not in the easy-to-get-to location by the fuses. I haven't yet checked the resistor that controls 1-3. I understand that's behind the glove box which I have not fealt like removing yet.

Any input appreciated.

Thanks,
Ben
