I'VE BEEN HAVING ISSUES WITH THE A/C UNIT, I TRY TO TURN IT ON AND ALL THAT IT DOES IS FLASH 3 TIMES AND THEN IT GOES BACK TO OFF, IT DOESN'T COOL AT ALL. I TRIED TO RESEARCH THE PROBLEM IN THE INTERNET AND AT THE GMC WEBSITE AND IT SEEMS THAT IS BEEN A HUGE ISSUE SINCE 2007 FOR THIS MODEL! I CALLED THE DEALER AND ALTHOUGH THEY KNOW WHAT THE PROBLEM IS THEY INSIST IN CHARGE ME $100 TO CONNECT IT AND TROUBLESHOOT IT EVEN THOUGH THEY KNOW THE ISSUE. THEY ARE CHARGING BETWEEN $ 1200 AND $2000 TO "FIX" A KNOWN PROBLEM. THIS PROBLEM IS CAUSING THAT MY CD PLAYER GETS HOT WHILE IS PLAYING THE CD AND EJECT THEM FROM THE SYSTEM. PLEASE I NEED YOU TO RESEARCH AND HELP OUT WITH THIS ISSUE. THEY SAY THAT IS A ISSUE WITH LOW OR LEAKING COOLING SYSTEM AND THAT IT NEEDS FREON OR THAT IS THE HVAC SYSTEM, BUT IS THE SAME EXCUSE TO HUNDREDS OF CUSTOMERS, SOME OF WHOM DECIDED TO JUST RUN THE VEHICLE WITHOUT A/C DURING HOT SUMMERS. BECAUSE OF ALL MY MEDICAL ISSUES, I CAN'T HAVE THE " LUXURY" OF NOT HAVING THE A/C BROKEN, NOR I HAVE THE MONEY TO PAY FOR SOMETHING THAT IS GIVING SO MANY PEOPLE SO MUCH PROBLEMS! THANKS *TR
