Ambient Lighting
so, it sounds like you only have it working on the passenger door. the only "switch" will turn off both at the same time -- it's controlled by the dash dimmer switch. if that switch is all the way up, ambient lighting should be on on both doors. if you turn it down, they should go off.
sounds like you might have a problem with the drive door.
if this is after market ABL (ambient lighting), then this is all irrelevant
