I have a 98 Outback and the fan only runs in #4 posistion or full blast. From the looks of the crappy Haynes wiring diagram it looks like it is not a fuse or relay problem, because obviously the blower is working in full blast. So through deduction I believe it to be the resistor pack has gone bad, and would like to know if anyone knows what type of resitances I should have if I ohm it out through the connector, and also the location of the resistor pack.
