'17 Impreza Limited. So when I turn the fan speed knob for the A/C / Heater up or down, sometimes it reacts correctly, sometimes it goes up when I say go down, sometimes it goes down when I say up, and sometimes it just does whatever the hell it wants. I need to keep turning the knob in different directions and hope it eventually lands on the fan speed I want. Just curious if anyone else has had this issue. I'm out of the original warranty but have the top coverage Subaru extended warranty, so it should be covered at the dealer. Just wondering if this was a common issue before I took it in.
