For some reason, suddenly, now when I apply the turn signal, even though only the selected side exterior lights flash normally, both dash indicators now flash simultaneously (like modern emerg. hazard lights). The indicator lights don't seem as bright as before, but it is hard to be sure. Before I dig out all the electrical manuals and start to sort this out, I am just wondering if anyone out there has had this exact same issue, and knows what is causing it?
