Just a question I found an article indicating that the climate control unit shows a number of test functions. The 11th one battery voltage, mine indicates 13 v with the engine running no accessories and 12.5 v with the front demister blower on, to me 13 v seems a little low the question is what would you expect the battery voltage to be?
If you would like to know how itís done visit go to the second article on the page. 2008 June | BMW E36 Blog
Just a suggestion have a tendency to press the rear defogger if anything a little before the auto button and donít press them for long. If you donít get it the first time keep trying you will. I accessed them with the car running.
Thanks for any and all help
