Anyone help got electrical fault with 04 t sport corolla entails no power to windows, radio, anything on the dash board or power steering. Been into mr ts local dealership who cleaned up the negative terminal on the battery and fixed problem. Driving home tonight from work and issue came on again now no power to all issues. Have tried disconnecting and reconnecting battery terminal but no luck. She starts and runs but no electrics. Checked fuses but no luck. Back into mr ts tomorrow for further diagnosis, any advice what it might be ?.
