switch on the steering column would not engage the cruise but would accelerate the car when pressed upwards.
It's the amplifier. Specifically, bad solder joints within same. Sure, it _could_ be something else, but of the dozen or so I've repaired only _one_ had anything else wrong with it (and I believe bad joints caused its H-bridge driver to smoke a transistor). The other eleven (or whatever) all did what you describe. Yours varies because going-bad solder joints are very temperature sensitive. Eventually they get worse, and then are bad all the time. Oh, I did have one obviously-flakey column switch, a gentle tap or a hard bump would cancel cruise. And my toddler tried to do a chin-up on one and broke it off, but neither of these were mysteries. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
