it's why there is a 35° switch in there to prevent it...

Yes, and thankfully that switch is working properly. After cooling down the cabin, on low fan speed the compressor cycles on and off (I can feel the slightest drop in power when the clutch engages). I usually roll the temp wheel all the way to the white to keep from freezing my arms. Of course on extremely hot days, it takes longer to cool the cabin, and the compressor stays running most of the time.
