We only handle one problem per thread so please start a new question for the dome light is not working. For the OBD2 connector not working we need to check for corrosion at the connector and let's check the fuse # 29 and #1 in the interior fuse panel under the lower left side of the dash. Here is the wiring diagram for the OBD2 connector so you can see how the system works and a guide to help you check the fuses for power.

Please let us know how it goes.
