If you're having problems with A/C not blowing cold or much pressure, have dealer replace the recirc door. (06's)That's what was wrong with mine.Dealer tech told me that 9 out of 10, that was the problem.There was alot of posts about this but I couldn't find them so I don't know if this is a repost.

 

Has the dealer checked the freon level?
Does it blow cold at all?
Does the fan soound like it's working?
Is the compressor comming on?
Bad fuse?

I had the same thing replaced in mine around a month ago. During the first real hot week in phoenix with the AC on high still roasting in the cab. Went to have the dealer ship check it out they replaced the whole air box assembly.

Before tacking it to the dealership I found that the glove box can be removed and the selector rod can be unjammed to make the AC work. This is just a temporary fix it tool only 3 to 4 times through the options to re-jam the selector door again. Best fix for a vehicle under warranty have them switch out the components in the system.
