I just want to add that, AC Control panel, when temp. of front both side are set to Hot(red), ONLY ONE SIDE changed to hot, since the other one STILL cold. The Control panel still displaying sensor reading without problem, but the DTC, diagnostic trouble code are not displayed. The procedures states , "place ignition in ON -position 1, but in pos.1 the control panel does not show anything, it happen on POS. 2. See what I did and the results: SENSORS: 1-9, 2-11, 3-72F, 4-72F, 5-67F, 6-64 F, 7-13, 8-24, 9-62, 16-0. For the Fault Diagnostic. 1- Turned left selector wheel to red and right to blue.2- Ignition On- pos.2, 3- AUTO button (both) automatically appeared ( it is standard in this car), 4- within 20 seconds I pressed REST and O SIMULTANOUSLY for 2 seconds, but NOTHING IS DISPALYED on left and right display.

Thanks again. Plaese how may identify the relay. My car does not has the chard for relay, only for fuses. Under the A/C wiring diagram the only relay is the Auxiliary coolant pump control relay. tHERE IS NOT AN a/c compressor relay?. Does the Base module computer releaf the relay?

I will appreciate your assistance
