My a/c takes along time to get going, especially the car has been sitting out in the heat for a few days. Sometimes, it will start blowing when I am at highway speed and I push the economy button and then open the sunroof. After that sequence it will start blowing..then I turn off the economy button and it starts blowing cooler air. Very Strange. Has anyone had this problem and if so, what was the remedy? Thanks

 

will it work without opening the sunroof ???????
