My 04 LeSabre has developed this issue of running at extremely high voltages. I've only had the car 2.5 weeks, so this is frustrating.
The dealer had a new battery put in before I bought it. Now, running down the highway at 65mph, the DIC reads out 15.1 volts, sometimes down to 14.8. The lowest I've seen on the car in the past 3 days has been 14.4. Never gone below that, even with a major voltage drop (heated seat on, and two power windows going at the same time).
My dash lights are all burning out, one by one. I've lost all the backlights in the HVAC, half the lights in the wheel controls, 1/3 of the lights in the radio, and both seat heater switches.
I would normally assume a bad battery, but it is (supposedly) new, and I have not had any starting issues, even running a bunch of accessories with the engine off for 30 minutes or more. It doesn't even hesitate to start.
Would this mean the alternator is going? Is he voltage regulated in the alternator or is it PCM controlled?
The dealer has taken the attitude with me that "Its a used car, its going to have some issues, its not perfect..", so I'm kinda screwed here.
Any help or ideas or test to do? Ive already pulled the dimmer switch down in hopes that it saves the death of the rest of my interior lights. I have a service manual on order, but it hasn't arrived yet, so I am at a loss as where to start here..
