Just ran outside and the ambient temp is down to 72 degrees. The lines are getting a little condensation and some frost on them and the temperature from the vent is still 40 degrees and I used another temp gun and got 28 to 35 degrees. I put the selector on normal instead of Max and lowered the fan speed. The clutch every minute or two disengaged for a bit and re engaged. So I think everything is fine and it was just a defective switch. As I mentioned earlier, it's just as cold as it was before.
Thanks to all for the information and possible reasons for the clutch being engaged all the time.
