Ambient temp is about 85ish </div></BLOCKQUOTE>Humidity has nothing to do with it. In a fixed orifice R-134A system (h2s) you can expect a temperature split of between 17-20 degrees across the evaporator coil. That means if 85 degree air is entering somewhere between 65-68 degree air should be discharging. This of course will come down as the cabin temperature cools down. So the discharge temperature will vary depending on load. Once the cabin is at temperature, say 72 degrees you should be getting a discharge temperature of around 55 degrees if you're recirculating. If it's not on recirculation and bringing in some outside air it will be higher.
