The value for #5 should be around 40 degrees F. The value for #7 is the high-side pressure measured at the receiver/drier. It will be low, around 6 bar at low ambient temp, and high (around 11+) at high ambient temp. A very glaring problem is that the evaporator temp is way higher than the left/right heater temps. Oftentimes the evap. temp sensor fails and gives these bizarre readings. #3, 4, and 5 should all be the same or very close with the compressor not running.
