This past Friday I had my altonater and ground cable for battery replaced. I brought my car in for service because the headlights were going dim when I turned on the air, rear window defog and such. My repair ticket said in part "Inspected charging system. With loads on only charging at 12.8V. Also inspected and found ground cable for battery. Found cable starting to come undone and corroded. Defective ground cable caused altonater to stop charging. Replaced altonater and ground cable for battery. Rechecked charging system. Charging at 13.6V at idle with loads on." Well, the headlights still dim when the rear window defog is turned on or the air is turn ALL THE WAY UP. HOWEVER, I just noticed that after I drove the car, the metal part of the key that goes into the ignition was hot. This was on 4 miles on local driving. Are these in anyway related? I am taking the car back to the dealer on Friday because the first problem was not totally fixed but this seems to be another problem. Is this an issue? Is this a fire risk? What could cause this? Am I perhaps mistaken because I do not think I am. What could cause the metal part of the key to heat up and is there any concern?
