a/c help 2004 2500 Express 6L V8
348,000 miles
Compressor runs on ALL climate settings bar one. The cabin circulation. Even in OFF setting. AC will run for a while and air flow gets less and less til it stops altogether. Turning dial to cabin setting and air slowly starts to return. Guessing the system is icing up to the point it blocks air flow and then it melts on the cabin setting. On HEAT mode, only cold air comes out the various vents an all settings, except CABIN setting. Any ideas? Dont want to start pulling it apart till I have a plan, as I use it every day.
