2008 Ford Escape LTD AC not cooling at idle
 

I love my Ford Escape, however my AC blows hot at idle only, when you are at speed it blows ice cold! Any suggestions? The fan on the driver side will engage, I haven't seen the right one yet engage. I'm not hearing any noises etc. it blows cold when your cruising on highway or surface, but will immediately blow hot when you come to a stop. I live in TEXAS and need relief fast! Help please! :eek:
