Problem symptoms: Car does not start. Instrument cluster, touch screen display, start button, windows, key fobs all show no sign of life. Car can only be opened manually with key.
What still works: Interior lights come on when I manually open the door, trunk release and gas door do open when appropriate button in car is pressed. Mirrors can be adjusted, hazard button and horn works.
How I got to this point: This winter, living in Chicago and with local dealer support no longer being available I decided to play it safe and leave the car in the garage. I had the 220V charger connected to the charging port, but did not realize until after closely reading this forum that I also should have put a battery tender on the 12V battery. Anyway, after a few months I noticed the 220V charger was lit red indicating a problem. I unplugged the charging port and plugged it back in and had the same problem. I started checking into things and found that the 12V battery was dead. I hooked up a 12V charger, noticed a clicking for a while (like a relay was going on and off) but after some time that stopped and the 12V battery now shows fully charged. I then picked up and connected a battery tender which also showed the battery is now fully charged. Now when I connect to the HV charging port, it appears to charge the high voltage battery fine because it showed charging for about three hours. I tried a hard reset however did not seem to change anything.
I love the car and am itching to drive it as soon as the weather improves. I am hoping it may be as simple as a blown fuse or bad relay. Please help. Any suggestions?
