good day, im mohammad koussa, from saudi, i have a cadilac seville. i used it since 1993 and i drive it very often and it was very good, but today, the air condition suddenly stopped.When i am pressing the AUTO button, the ECON option is the one appearing on the screen and no air is coming out. i don't know why does it happened when i pressed the auto button which it is the option used to make the temperature cold suddenly it shift to ECON. Kindly help me with my inquiry because i took it to many auto shops, they dont know how to fix it. It will be a pleasure on my part if i can hear something from you. thank you.

sincerely yours,
mohammad koussa
