Evaporator temp MUST be less than heater core temp!
Refrigerant pressure in BAR should be between 4-8.

M.B.DOC, I am inclined to agree with you regarding the evaporator sensor because I got the high temp reading with the engine not running and the car having sat parked for almost 24 hours! From reading other similar posts here, it appears the sensor is located somewhere under the driver's footwell?
The next obvious question then is, how do I go about replacing the sensor? How much does the sensor generally run? And is it a part I can purchase from the forum parts store?
As for #7 and the refrigerant pressure, could it be because the compressor is not really kicking in due to the high sensor reading? Also, the pressure gauge I used is one of those that you purchase or come with R134a cans in the store. It has both a color and number coded gradient going from 0-200psi and the colors green(Low)/blue(Filled)/yellow(Alert)/red(Warning).
My instinct is to replace the evaporator temp sensor and then go from there. Can I hope for any guidance in replacing the sensor from you or any other forum member? And, thank you for your input thus far.
