Thanks for the reply. I'm waiting for the actual values to both questions from the dealer. They keep teling me the pressures are within specs. It seems like every question I ask they want to run it by Ford.
What should the hi/ low pressures be when running and at rest when they hopefully are equalized?
Is there a high pressure switch? Or do they do fancy magic (math) with the computer & the evaporater temp sensor to calculate the high pressure?
I guess I really want to know how the system works, the window/range for each sensor, and what sensors are really used. The folks at the dealer can't answer any detailed question. For example; what is the range for cycling the compressor if it's the evap. Temp sensor? 33F to 38F to cycle on-off?
