Last month I purchased a 1987 260E with just 80k miles. After minor cosmetics, we have a great car considering the $2500 purchase price. During my last trip in the car, I noticed that a tick sound started coming from the passenger side front interior, sounds like it is coming from under the glove box. It sounds like a relay? ticking similar to the sound that the blinkers make. Once you shut the car off, it still DOES NOT stop. The ony way I can get the ticking to stop is to disconnect the battery. I have not noticed anyting that does not work properly, making this a bit of a mystery. Before I tear into the interior, I wanted to ask anyone if they had any thoughts as to what might be ticking? Thanks for any help.
