Alternator, Electric power steering, Stereo, A.C. fan, Power windows all stop working individually and sometimes in groups. I can usually make them start working by turning the ignition off and back on. It happens more and more frequently and sometimes does not charge. I have replaced the battery and had the alternator tested as good. Even a bad alternator would not explain ALL the electrical demons I have encountered. HELP!!

Sounds like low voltage or poor electrical connections but could also be the ECM – Engine Control Module failing.
Thank you. How would I test for this ECM failure?
This would require a Dealership and their diagnostic equipment.
