When cargo lamp button depressed the cargo lamp "on" indicator on dash illuminates, but cargo lamp itself does not illuminate - test confirms no power at cargo lamp location. Further, and somehow related, the overhead reading lamps do not come on when the individual overhead panel switches are pressed, but the cargo lamp indicator illuminates! Those reading lamps do actually come on in all other modes, just not when selected individually with the respective switch. The overhead switches DO turn the respective reading lamp off when the interior lights have been turned on by other means. e.g. when door opened or rheostat switch by headlight switch is used. Any thoughts?? BCM? Evil spirits? Anybody have a schematic?
