Radio continues to play

Battery recharge may now be necessary. Good luck!

Dome lights, power windows, nothing else worked with no power except radio. Could turn it off but clock remained on, only way to shut it down was to pull negative cable. Immediately came back on when negative terminal made contact. Played with passenger side power window switch and it eventually shut radio off and has worked fine since. Left windows down last night and it rained, so thinking water caused the problem somehow. Made 2 different short trips and problem hasn't re-occurred! Who knows???
