Random warning chime (the one you hear at start up or when ebrake is on) coming from my 2005 Rubicon. Seems to happen at speeds of 30 mph and above with headlights are on. When I come to stop, chime goes away. All gauges are reading proper levels. Other thing I noticed was left turn signal indicator on dash was barely illuminated when I went to shut off motor. Chime was not going off at this time. Flipped turn signal, light went off. Any suggestions?
