I just purchased a 2004 Pilot for my daughter to drive to and from school. The dash lights work fine when the headlights are off, but as soon as I turn the headlights on, they go so dim I can’t see anything. I get nothing from the dimmer control on the speedometer. Just a side note, The previous owner had installed a crappy after market stereo, which I replaced with a factory unit thinking that might be the culprit but it has had no effect on the dash light issue. Any ideas?
