So I have a 2003 durango (4.7 ), I got it back in 2008. It worked fine until winter rolls around, it cuts off when idle (like at a red light), but now I'm having trouble with the a/c. I just got the blower and a/c compressor replaced but it is not blowing air at max. I need to know if I'm not the only person with this problem.

 

Dying at idle is usually a bad battery/battery connection or a dirty IAC. Cleaning the IAC and cleaning battery connections are both easy and free so I'd start there.
