ashok540 0 Report post Posted July 9, 2008 (edited) I find that the frequency of my a/c not powering on automatically when the car is started has increased quite a bit. Now this happens almost all mornings, when I first start it for the day. About 3 minutes into my driving, it comes on and behaves completely normal for the whole day! And no associated dimming of music system or any other lights. While it is off when I start the car, I cannot manually turn it on either, all a/c keys are unresponsive. Could this be some loose connection? Car is E39 540i. Edited July 9, 2008 by ashok540 Quote Share this post Link to post Share on other sites
