I have a 2004 Dodge Grand caravan SXT. Recently my ABS light on the dash has come and stayed on. I also lost the traction control due to the light being on. Last time this happened, it was a frozen sensor. So this time I've parked inside for a couple of days, removed the wheels and sprayed hot water to melt the snow and ice. After all was done I removed the battery to reset the computer. Still today the light is on, with no ABS or traction control. What else could it be??

Thanks,
Jay
