The sensor values at 9 and up won't kill your AC, so I didn't ask for them. Some of them have absolutely no meaning according to the diagnostic manual; I don't recall exactly which though.

I expected to see a very high value for #5, the evaporator temperature sensor. It is not, assuming that your climate control sensors read in F and it was really about 67F inside the car when you did the test.

The next step is to extract trouble codes from the system. The pushbutton unit can do these also. Here is the procedure:

Ignition ON
Temperature selector left "HI" right "LO"
Within 20 seconds, press REST and EC simultaneously for more than 5 seconds
The LED in the recirculate button flashes and the display shows "di R"
Press AUTO repeatedly until all DTC's (refer to DTC table) are displayed. Record each DTC as it is displayed.

To erase: Only possible after all DTC's are read out. Simultaneously press both AUTO >2 secs. "d" will be displayed in the left side of the display window and "FF" on the right.
To cancel erase: By pressing AUTO the current faults will appear again.

Set the temperature selector to normal setting
Turn the ignition OFF to end test.
