How about a CX350D
The evap was/still partially plugged up. Since I can't access it without stripping the entire HVAC unit out, I cleaned it best I could. Thanks for the advice, but I'm not going to open the system.I have a caterpillar chart I'll post up tomorrow.
I would evac system. It's obviously not leaking but double check it hold vacuum. Should pull 28-30in. Then replace dryer and expansion valve and make sure the evaporator isn't clogged with dirt
... Had plenty of dirt/mud/whatever all over it. Not sure how that crap all got in there, since the fresh air and the re-circ air both have filters...

Actually, on these particular Case machines, the light sensor does affect the cooling, IF the ECM determines that it needs to. I know this because there is a diagnostic screen for strictly the A/C system built in. It reads a multitude of things, among them the evap temp, incoming air temp, and sun load. Not trying to be a smartass, but it is a fact. Also, I notice that it isn't a perfect system, because it will run cooler on a bright, sunny day than it will on a cloudy day. On my machine, I will have to set the target temp higher on a sunny day than cloudy, also need to turn the temp DOWN when the sun goes down and it's still hot out.The A/C system -is not- controlled by the light sensor.
The sensor sometimes controls such things as lights and console lighting, depending on the device.
A/C systems are quite simplistic in function and operation. -Their output- (airflow, Etc) is -sometimes- controlled by temperature sensors but never by a light sensor.
