Yeah, the AC was working, it just took a while to get cold & once warmed up it was "cool" but not really cold. Been like that for about a month. Since the compressor shutting on & off is not normal behavior (I thought it was!) on the WRX, I might go pick up another can today & see what the pressure does when adding it to that car, compared to the Forester. Also, good to know about the 40psi spec in the Legacy manual!
