DOME ON DOME OFF

[soundlubber]

+-----------ANYONE HAVE THIS PROBLEM? I GO TO OPEN MY CAR DOORS AND THE LIGHT DOESN'T TURN ON. NEXT-IT WORKS FOR A WEEK. JUST WHEN I GO TO BUY A BULB THE DARN THING WORKS AGAIN. THE KEY/ENTRY LIGHT WORKS AS DOES THE DASH LIGHTS. CAN'T FIGURE IT OUT. IT'S NOT INTERMITTENT AND I CAN'T MAKE IT GO ON. I LOOKED IN THE MANUAL FOR A POSSIBLE PROGRAM WITH THE KEY SWITCH WITH NO LUCK. LIGHT WON'T TURN ON IN ANY POSITION. PUSH-ON MAP LIGHTS OVER THE MIRROR ARE FINE.
