the interior light diagram shows 3 door controlled lights: cargo lamp, front interior/map and rear interior/map.
the lights have all have 3 wires; grd, manual power and door actuated power. we know the grd and manual power work, as the manual switch powers the light. if all 3 lights do not work in the door switch position, you need to check for power out of smart junction box located behind the left side of the dash. if no power is present on pin 21 orange/white wire with the door open...the module may be bad. if there is power, you have a broken wire somewhere between the module and splice 906 of the interior lamp harness.
if only 1`of the 3 lights is not working, remove the connector to this light and check for power on the orange white wire; door must be open. if you have power, the light switch is bad. if no power, there is a open wire on the branch of the orange/white wire that feeds the light.
