Hi, I had read the post regarding non-german tail light bulbs being a possible problem for cruise control. Sure enough, I changed mine and the cruise works! I thought I was going to have to buy a new amplifier or actuator, or both! I REALLY appreciate the tip! Too bad the cigarette butt trick didn't fix my tach, but I'm thrilled to have cruise for less than $2.00!
