I purchased the 2015 maserati ghibli sq4 nov 2015, and after 2000 miles the car had a problem with the air condition stuck in defrost mode. took the car to the local dealer for service repair and they found the issue with the air condition solenoid that was replaced. then i started having too much front windshield defrost and it covers my front view. to reproduce the concern start the car and open up the 4 windows drive up for more than 15 minutes, then stop the car close the windows and turn of the engine. come back after 10 min or more start the engine, roll down the windows and start driving. you'll feel the heat inside from the engine inside the car, and you'll start seeing large amount of defrost inside the windshield even the windows rolled down. i had to keep turning in front and back defrost and the air condition. turn off the air condition keep driving then the defrost will come back again and the only way to eliminate the defrost you have to keep both defrost and air condition on all the time. the service shop stated this is working as designed. please advice!
