2015 Subaru XV Crosstrek - Fan Problems

Fan has been acting up lately, so I wanted to see if anyone could help me out and figure out what’s wrong with it. Recently the fan started not blowing at all if I have it set on 2. 1, 3, and 4 have been working fine. I’ve also noticed if I have it set on 3 or 4, sometimes it’ll blow a lot more than normal for a bit. Yesterday morning, fan wouldn’t blow at all. Tried it again after work, and it was back to blowing normal on 1, 3, and 4.

Any guesses as to what might be causing this issue and if I could possibly fix it myself? Thanks!

You have described classic symptoms of a bad blower motor resistor.
If you are reasonably handy, this is likely to be a repair that you can do.

The next time the fan stops blowing, with the fan speed set to high, reach under the passenger side dash and with the handle of a screwdriver, rap on the blower motor.

If the blower starts working, replace the blower motor.
