First, welcome to the forum. Second, in order to understand the written english language one generally needs punctuation!!

I would start by checking to see if the A/C system is charged with enough refrigerant and to be sure that the condensing coil in front of the radiator is not plugged up. Next, you would have to start eliminating the possibility of bad sensors (sun load and ambient cabin air temp) and faulty blend door actuators. Complicated system and you may have to go to the dealer for help in the end.

Dude! welcome. And good job on the punciasen (pun).

For a good time, go to ACkits.com and then to their forum. Best A/C forum around. The owner of the biz is in Arizona and he is great. He frequents the forum and helps as well as other A/C techs. Parts and tools from them are great prices and he researches the quality. First thing you'll need is a set of gauges. Don't buy them from Kragen or some such autoparts store (like I did) or you'll be buying a second set (like I did).
