problem with sunfire

hey I would like to know if someone could give me a hand . Ihave a 2000 sunfire GT 2.4 , i've got one high beam that doesn't want to work and my daytime running lights flick on and of when putting it into drive, the service light comes on and off for the ABS and TRACTION CONTROL. I've changed a speed censor but it didn't help, mechanic wants to change the wireing harness, as for the lights I've changed the bulb, and daytime running lights relay in the fuse box but still no high beam or daytime running lights.Any suggestions.dave

Have a mechanic hook up a scan tool to your vehicle. If the ABS and Traction Control lights are coming on, then there will be stored trouble codes to help diagnose the problem. The problems you describe could be related or may be separate. Start with the scan tool. It could be as simple as a bad ground. GM uses only a few spots to ground many different components.sparky

ya we did that after we had changed the speed censor on the passengers side front he put the computer on the car and it read everything backwards , he sun the back drivers side and the front drivers side was showing on the computer, thats when he suggested to change the whole harness, and no the sterio is the original monsoon sterio.dave

i can live with out the abs and traction control but the high beam i would like to work.dave
