How about a make, model, year... But, on my ProStar, it was a bad compass module that set those off on my dash. Compass module, as in North, South, East and West... Try replacing the fuses too, they tarnish and will test good, but in reality they ain't. Another issue of the ProStar. User's Signature: 2008 ProStar, OEM 600hp CM-871, 18spd, 3:42, in framed in Rawze's driveway. Every day is a fresh new episode of, "The Twilight Zone"... Rod Serling lives rent free in my head. I can smell the Chesterfields. | |||
