First off, yes, I have checked and replaced my battery and my alternator. I am getting intermittent flashing of my battery, doors, and trunk lights. Not all the time but it will just flicker on and off. Seems to be related to when I touch the gas pedal and it will come on-release the pedal it stops. Touch the gas again it will flash again. Never stays on for any period of time, but I have had the battery and alternator tested by Advance Auto who hooked it to a large handheld for the battery and I actually brought in my alternator to have them hook it up to a machine. They ran the test 7 times and it worked like a charm. So frustrated, and I am worried my wife is going to be driving it someday and then there will be a major failure of some kind. Anyone have a problem like this? Any bulletins out there I should be made aware of?

 

These problems occur due to loss of power or loss of ground. A bad battery connection or bad battery cable/s are usual source of the problem. A loose ground to engine/body could also cause this symptom.

good luck
