Howdy all, recently my ventilation system started only blowing when the knob is turned to 4, so it's full blast or nothing these days. Anyone else seen this before? Browsing the forums I've seen some people run into this with the Legacy and they mention a  wire or switch below/behind the dash, but I can't find anything similar on my GL

Could be blower resistor triple in bottom of heater/AC blower on R side. Check bottom 2 15 amp fuses on LH side of fuse panel too.

However, if its like my GL some contacts in fan speed switch have fried.

As mentioned - check the resistors in the fan ducting. There will be several wires that plug into this device. 

Check those and go from there to the switch etc.

Cheers
