Hazard Flashing Warning Light Unit problems of the 2002 Ford Windstar

Abs and brake lights come on intermittently. I applied the brakes heavily and all 4 wheels locked up. The vehicle was uncontrollable while braking. The speedometer is erratic. The battery is dead sometimes after sitting overnight. The hazard lights come on by them selves. The door locks do not work properly. The tire indicator lights come on for no reason.

Our 2002 Ford Windstar had the abs and brake warning light come on while driving this happens at intervals with no apparent connection to weather, driving speed, etc. The lights will go off when the van is shut off and restarted. I have not made an appt with my mechanic to check the problem as of yet. On 11/26/2008. While traveling at night on an interstate the abs and brake light came on and shortly afterward the headlights dimmed. The air bag and battery light came on and the turn signals and headlights stopped working altogether. We were able to pull off the road completely. Shut the van off and it would not restart. Turned on the hazard lights and waited for help to arrive after calling 911 on cell phone. The hazard lights stopped working on the front of the van but continued to work in the rear. The interior lights started blinking and would not shut off at all when pushing the switch. The rear hazard lights also would not shut off when the tow truck that was dispatched arrived. Vehicle was towed from the interstate to the nearest vehicle repair garage. Garage has not been able to look into the problem due to the vehicle breaking down the day before thanksgiving. Garage will call on Friday after they have looked into the problem.
