I have a 2000 TJ sport. There is some sort of electrical problem going on. Sometimes when I start it the gauges on the instrument cluster will not work, sometimes blinkers don't work, sometimes the wipers won't work, sometimes its the radio, and other times its the air. It is usually not everything at once that doesn't work, it just depends. To fix it I just kill the engine and start it back up, this usually fixes the problem. Also sometimes the right or left blinker light on the dash will stay lit up, when it does this the blinker is constantly lit. The check engine light has been on since I got it but there are not codes. Any ideas?
