My wifes A/C in her 06 TB stopped working. I'm not in the area and trying to diagnose over the phone. Says the AC blows just not cold, but every once in awhile a puff of cold will come out. Any suggestions? and a few weeks ago she got P0128 but it never came back.

About all you can tell over the phone is if the A/C fuse is OK, and if the compressor clutch is kicking on. But, that's if you know what to look for and where. A set of A/C gauges will tell you a lot more, but obviously you can't do that over the phone.
