HiHi Why is the player hot with the key off, it should time out like the rest of the accessories? Hard to say, with over 2,000 codes just to run the engine I have no desire to check out all the "U", "C", "P", and "B" codes to find one by a word search. You need the failure code to start tracking a problem. |

The tech was trying to find the short or whatever that killed two batteries. He was having to do it the old fashion way * one circuit at a time. The service writer called back at the end of the day saying the new battery was okay that it charged fine and the tech found the interior lamp ON so he turned it OFF. The excessive current draw stopped but he wanted to let it sleep over night in his stall and check it in the morning. They called Tuesday and I have the car back. For only $114 we went from Intensive Care to Release. I have no idea how the interior lamps got turned ON but it was dying on me during the day and I probably never noticed the lamps staying on. The lamps turn ON when you open the door and they stay ON when you close it for about 30 seconds. The same set of lamps double as Map lights with two ON/OFF buttons in the mirror. I do not remember turning on a map light but may have done by accident the last time I washed the car and cleaned the mirror. The last wash was the morning before all this crap started. Dodged an expensive bullet on this one. The real test will be to see if it starts after spending the night in our garage |

Check it out. Strange they got 4 amps one time and 6 this time. |

In that model there was a little metal tang next to the headlight switch to turn inside lights on. I guess when turning headlights off I kept hitting it. Went from a new battery every year to one that has now lasted four years. G |

It > can be done by your left knee on the dash. Check it out. > > Strange they got 4 amps one time and 6 this time. I called and asked the service writer about the 4 vs 6 amps. He wrote down 4 from his discussion with the tech on first test but the tech notes on the invoice for what he found said 6.25 amps. The 6.25 may be after they installed the recharged battery. On the same follow up call I asked about the map light and he said it was the pot on the dash dimmer lights. I just tried it and when you roll it just past high, the interior lights come on. I could have done that cleaning the dash. I tend to forget about the dash dimmer switch |

As a test he had me pull the connector to do a reset. It is hot all the time. |
