We have a 2004 Honda Accord. The car was in the garage for six months while we were in Alaska. When we returned the battery had gone dead. We charged it and it is fine. The radio’s anti-theft device had disabled the radio. We re-set it with the five digit code. The other problem is the dash lights. They work fine when the headlights are off but when you turn the headlights on the dash lights go out. I turned the dimmer wheel in both directions with no effect on the dash lights. Please advise how to get the dash light to work with the headlights on.
