Mind you, today's ambient temps were about 87 degrees.
So I guess the problem with Mercedes a/c systems is not that they don't get COLD enough, there's simply not ENOUGH of the cold! They need more volume of it, to take car of all the heat coming into the cars, by way of the sun's rays.

These values are not correct. The infrared device is providing false readings due to varying reflectivity. If the air temperature ever drops below 38 degrees or so, the evap freezes. The system is designed to prevent this under all circumstances.
Go out and spend the $5.00 on a proper thermometer............like I suggested in post #11.
