Thought I had a short somewhere, but I'm not so sure now.
Initially, I went out to start my truck, when I started it the door ajar light stayed on, and so did the dome and cargo lights. The only way I got the dome light off was by turning the dimmer switch all the way down, to the level just above the dash lights being off. The cargo light would not turn off, and neither would the door ajar light (yes, all the doors were closed)
After pulling the fuses to get them to go off, they stayed off when the fuses were put back in.
The next morning, my radio came on when I turned the truck on, but once I started it, it wouldn't work. It was still getting power, as the clock would still display when the button was pushed. That is now an intermittent problem.
Just tonight I noticed the headlights dimming a bit, then coming back up, as well as the heater fan (simultaneous.)
Any thoughts? Haven't checked it out thoroughly yet, voltmeter in the dash shows just over 14. There's no fluctuation in the meter when I turn on or off any electrical equipment.
Maybe check your batteries if one is starting to take a poop it will mess with other and vice versa, if your volt meter or amp meter is showing 14vdc doesn't mean the battery or batteries are holding the charge and computer doesn't like it.
