READING ACTUAL VALUES:--------AC must be running to retrieve actual values!!
Ignition---position 1
Press the auto button and set temps to 72F or equivalent C
Press the Rest button for 5 seconds or more
The left side of the display will show number"1" and a value for In car Temp
Then press Auto again for the next number and corresponding value
Keep pressing and writing down the numbers and values till "12"
To end the process press Rest----you are half way done!!


READING FAULT DIAGNOSIS:

Ignition in position 1
Set Left Temp to HI
Set Right Temp to LO
Within twenty seconds simultaneously press the rest and EC for more than 5 seconds
The screen will flash "dl R"
Now press the right Auto button one at a time until all faults are displayed and recorded
All faults must be read out before they can be cleared.
To clear all faults press both auto buttons for more that 2 seconds and a "d" will be displayed on the left and "FF" is displayed on the right

Now go back and reset you cabin temps---ignition off------end of test

Good Luck and after clearing the faults there will be no red light on the EC button, but will return if you do not fix what is faulty.

In your case that will be late summer, Oh well

Had the same problem, try having the hi and low temps opposite of what the directions tell you to. It worked with me that way
