I have a 2002 100 series TD4.2 Australian delivery GXL. The AC is a single zone non climate control unit. I am finding that the evap coil is icing up due to the compressor clutch running continuously. my question is I guess the clutch would be controlled by a temp sensor somewhere near the evap coil, I have pulled the evap coil cover off and couldnt see anything, is there a thermostat somewhere else in the system, or anything else that I should be looking at. I have had the gas pressures checked and the tx valve is working as I can feel the temp change in the return pipe. any suggestions, thanks.
