Typical subaru air conditioning problems explained.
Six problems related to air conditioner have been reported for the 2017 subaru forester.
The most recently reported issues are listed below.
The ac blows cold and occasionally a low pitched moaning sound like a goose is made appearing to come from under the dash.
I have a 2003 subaru outback wagon with exactly the same ac noise issue.
What do you do not hear is the clutch engagement when i first turn.
It also seems to get slightly more humid and a little warmer right after the noise is made like the outside airvent has been opened.
Need help figuring out what s causing this noise.
