    If you want to fix this yourself, you'll need to educate yourself on exactly how this system operates, then start to diagnose accordingly. I suggest a Bentley Manual from http://bit.ly/Bentley_Repair_Manuals

    Manual is always good. You have filters internal to the cars ac and they get dirty, find them and clean them.
