8:06 AM 8/8/2008
Hey guys.. this problem started about a month ago.. at certain rpms depending on the load put on the battery (ac/heat on) , the abs light an brake light flashes on my dash, as well as a low battery charge display on the digital display.. wen the ac or heat is on it flashes @ lower rpms... but regular a 2 about 3000 rpms.... got my alternator checked out an it passed.. regular voltage while the display is sayin low and the lights were flashing.. also the lights in the car get slightly brighter when this is happening.. guy @ the shop said its probably my computer..(but this is sears were talking about here, soo i want a second opinion)
what could this be.. and where is the computer soo i can change it if i need to.. i hear its eather under the dash or on the right passenger side kick panel.. thanks

I'd suggest a VAT-40 test, that will determine if there is a battery, charging or starting system issue with your car. Parasitic draw is also a possibility, but start simple. Does the battery ever die if the car is left sitting for a couple days? How many times has the battery been completely drained in the last 6 months of ownership? Lead-acid batteries will loose their ability to hold a proper charge if deep-cycled too many times. I reccomend gel-cells for this reason.
