Inspect the (DCCV) Dual Coolant Control Valve, under the hood lower front right. Use a multimeter to check voltage on circuit for Brown / Green drivers side and Brown / Light Green passengers side. Set temp to 60 expect 3.0 volts as increased to 90 voltage should increases to 9 volts... check both sides If OK,Try the self-check feature on the A/C. To test the A/C on your car do this to the A/C panel: With the car running and the A/C off: Press the OFF and DEFROST buttons simultaneously, then release and press the AUTO button within two seconds. Let the test run...it will last about 30-45 seconds. If any numbers are displayed, write them down. Press any button to exit the test. WAIT one minute before doing anything else, including turning off the car...DO NOT, do anything for at least a minute.
