I did actually include in my two previous posts that I have actually already gone through the diagnostics in the MBZ climate control service manual up to the point where I need a $400 dollar test fixture to check the electrical components of the ACC. .. > > Ideally, I would like to run the electrical component test using the nice breakout box/test fixture that Mercedes shows in the ACC manual, but I cannot see spending $400 plus dollars for a very specialized tool.
